Statistics for Data Science

Today’s lecture for Big Data Analytics included statistical tools for data analysis.

My Data Pro Tumble blog includes several listings and resources concerning statistics <>.

From the perspective of an information scientist, statistical analysis software is not just the computation done, but preservation of both the input, output, and processing.

One of the more popular statistical software packages is R, which actually does a lot more than work with statistics (as one of my recent tweets showed):

There’s a short introduction to R which explains:

R is a tool for statistics and data modeling. The R programming language is elegant, versatile, and has a highly expressive syntax designed around working with data. R is more than that, though — it also includes extremely powerful graphics capabilities. If you want to easily manipulate your data and present it in compelling ways, R is the tool for you.

It’s also possible to run R from the terminal in Mac OS X, but a nice interface for using R is R Studio <>.

Environmental Layers for HPC Maximum Entropy Species Distribution Models in Great Smoky Mountains National Park

Currently there are 10 environmental layers that were used by Simmerman et. al in the demonstration project, “Exploring similarities among many species distributions.”

  1. Bedrock geology
  2. Digital elevation model
  3. Slope measured in degrees
  4. Solar radiation data
  5. Soil organic type
  6. Terrain shape index
  7. Topographic convergence index
  8. Leaf on canopy cover
  9. Understory density classes
  10. Vegetation classes

The contribution of environmental variables to each “Maximum Entropy” Species Distribution Model (MaxEnt SDM) environmental variables are accessible from each model under the “Environmental Layers” tab.

The help icon accompanying each model provides this text:

This is a species distribution model (SDM) produced by MaxEnt. This SDM is actually a composite from ten cross-validation runs for each species (see cross-validation results tab for more information). Original ATBI record locations are shown with black dots. The color scale goes from 0 probability of presence (dark brown) to 100% probability (dark green).

Color distribution depicting a probability between 0 (no chance of finding a species) and 1 (100% chance of finding a species)

Below is a screen capture of the model generated for the Fraser fir (Abies fraseri). This model is based on 474 occurrence records.  The full size image is available online at <>


SDM model generated by the ATBI mapping project / University of Tennessee SEElab.

Interestingly, the MaxEnt model output suggests that the “Digital Elevation Model” contributed 88.8% to the Species Distribution Model for Abies frasieri.  This makes sense, since the Fraser fir is a species of conifer favoring cold environments that inhabits only the highest elevations of the Park.  The remaining layers contribute less than 5% to the model.

I’m copying out the taxonomic classification from Wikipedia:

Scientific classification
Kingdom: Plantae
Division: Pinophyta
Class: Pinopsida
Order: Pinales
Family: Pinaceae
Genus: Abies
Species: A. fraseri

The purpose is to access the records from the ATBI database, where I don’t see the Fraser fir listed in the ATBI “plants” kingdom. From <> I searched by “order’ for “pinales.”

Fraser fir is accessible: <>.  Interestingly, the number of specimens in the database is 866.  Contrast this with the 474 records that were used to generate the model.  The model may simply be older (there does not appear to be a timestamp for the model; either from “Get Info” or opening up “Properties” in GIMP for both the large 299×1302 pixel PNG file and the small 600×269 pixel png) or, not all 866 occurrence records have spatial coordinates associated (e.g., they are “references from the literature.”)

Poster for North Carolina Partners in Amphibian and Reptile Conservation

Poster might highlight the MaxEnt model as an example of the outcome of research in the park and emphasize the need for more occurrence data to populate the ATBI database. 
As of Feb. 24, 2014, there are no reptile species modeled already by the All Taxa mapping project.
Some simple facts might help illustrate the need for more reptile data:
  • ​total herp species in park
  • total herp species in the ATBI database
  • total herp species in the ATBI database that have n = 30 or more
  • total herp species in the ATBI database that need more data to be modeled
I think n of 30 or more was settled on by convention in hopes of having a normal distribution (Central limit theorem).
I just looked at this issue for plants – ATBI has ~1,600 vascular plants, but only around 500 have data points that can be modeled.  And of those, 257 have the requisite 30 or more occurrence records.
Total herp species in the Park according to ATBI database:
Class Amphibia – 63 species
Class Reptilia – 41 species
I’m not sure where to get a “species checklist” for total herp species in the park.  Since the ATBI database is “All Taxa,” it seems that yes, all herp species would be included.  However I don’t know that this is true and it would be nice to verify against another source.
It is interesting that the species with the highest number of records is northern copperhead (Agkistrodon contortrix mokasen,) with 233 specimens, followed by the northern black racer (Coluber constrictor constrictor) at 181 specimens.
I took some .tiff images, saved in “Documents/NPS-NICS-Practicum/herpetofauna/ATBI-reptiles-022414” convert to PNG using GIMP (GNU Image Manipulation Program).

Vascular Plants in ATBI Database Suitable for MaxEnt SDM Modeling

This afternoon I have established a few facts concerning plants in the Smokies.

The ATBI database (available to me on public server) has 432 vascular plant species for which there are 30 or more occurrence records.

This is out of 2001 entries – although the ATBI database reports “1643 species” for subkingdom Tracheobionta. So, 432/2001 is about 21% species that have 30 or more records.

The SEElab already has maps for 225 plant species. (SeeLab-Plants-Mod)

I combined the SEElab plant list (n=225) with the ATBI vascular plants list of more than 30 records (n=432), then filtered for unique records based on scientific name.

This yielded a total of 257 scientific names, suggesting there are 257 plant species from the ATBI database that have NOT been modeled by SEElab.

I have attached this data in the .csv file, “Vasc-Plant-Unique.” Perhaps this is the roughly 257 species Keith Langdon mentioned to me on the phone?

I don’t yet have access to the Nautilus supercomputer so initial runs would need to be done on a PC. I can make my documentation for running individual models on a PC by doing these first runs.

With the refined list of ~257 plant species, is there a preference for particular species or species assemblages?

If there is no preference for a particular plant species (out of those that have the requisite number of 30 or more records) I could just do some species modelling for Hemlock forests, as there is literature available for me to reference and it is interesting to look at potential community impacts from the HWA.

I’m having some trouble forwarding the .csv file to NPS staff (filtering, probably a security risk).

And, WordPress is not letting me upload any file other than a Microsoft .xls file. This is poor data management practice; I should archive a plain text or .csv file. So, my solution for the time being is that I believe I will paste the plain text here:

Spring 2014 Practicum Application

Student’s SIS Advisor’s Name: Dr. Suzie Allard
Name Student’s Practicum Supervisor: Tom Colson; Scott Simmerman
Number of Credit Hours for which you wish to be enrolled in the practicum: 3 hours
Semester during which you wish to be enrolled in the practicum: Spring 2014
Briefly describe prior and/or current information or library work experience:
I am interested in a career in environmental information management,
particularly in a governmental natural resource management agency. My course work to date includes classes in geographic information science,
environmental information management, and data visualization for
environmental science.
Indicate the type of information organization in which you wish to take the
practicum: Environmental Information Management Org
Practicum Location: Great Smoky Mountains National Park; National Institute for Computational Sciences

Practicum Objectives:
I would like to develop advanced environmental information processing and
data visualization skills by working with species occurrence records and a
high performance computing environment as part of a technology transfer
project between the University of Tennessee and the National Park Service.

The following four practicum goals and associated outcomes are proposed for
this project:

(1) Develop proficiency in running the MaxEnt species distribution modelling
program in a PC environment for determining probability of species
distribution given environmental variables and demonstrate acquired
proficiency by providing training and instruction to Park Service staff in
use of the MaxEnt program on Park resources configured to run MaxEnt.
Training materials and sessions will be produced as an outcome of the
(2) Gain skills with workflow and parallel processing in a high performance
computing environment on a single-system-image supercomputer and demonstrate these skills by generating species distribution models as requested by practicum supervisor. There are currently 540 species models out of ~36,000 species in the park. A collection of new models will demonstrate the outcome of the practicum.
(3) Create documentation for running the MaxEnt model in a PC environment using appropriate technology such as a wiki with walkthroughs, screen captures, or video screencasts as appropriate. A URL will be provided to the final online documentation to demonstrate the outcome of the practicum.
(4) Practice sound data curation principles in managing both model inputs and model outputs by successfully building on the store of models available at . An HPC data management system such as XSEDE ( will be used to manage the inputs and outputs to demonstrate the outcome of the practicum.

In a rough estimation, I expect to spend about a 1/3 of the required 150
hours learning MaxEnt on PC and HPC environments, 1/3 writing documentation, and 1/3 creating and delivering training (to commence in March, 2014) to enable NPS staff to implement MaxEnt modelling on both PC and HPC platforms.

Presentation – Geocoding in Geographic Information Retrieval Systems

I presented this paper at the Geographic Information Systems II (GIS II) session at the 2014 Geography Symposium (See UT Geography Symposium Program 2014)

I represented The University of Tennessee School of Information Sciences at this interdisciplinary conference themed “Mapping outside the lines: Geography as a nexus for interdisciplinary and collaborative research.”

Tanner Jessel, School of Information Sciences, University of Tennessee. “Geocoding in Geographic Information Retrieval Systems.”

Information with a geographic component is among the most valuable and sought after types of information. However, the majority of geographical information exists as indirectly referenced locational information within unstructured text. Even among well-annotated, spatially explicit datasets, existing metadata can be of sparse, inconsistent, or otherwise of poor quality due to time and budgetary constraints. For these reasons, automated annotation of spatially explicit coordinates, a process known as geocoding, is an active area of research in geographic infor- mation science. Research concerning geocoding represents a long-term effort with a body of knowledge that has grown across several decades. Unfortunately, funding cycles are not always long-term, and some groundbreaking technologies and tools are no longer available. The present article attempts to synthesize the current state-of-the art of geocoding and presents a “toolkit” of resources used across the literature to accomplish geocoding, with an emphasis on applications for geographic information retrieval.

Extraction, Transform and Load

A friend of mine in the program commented that about 90% of the time doing data science is obtaining and cleaning data.

This is where programming is incredibly useful.  In the second year of my Masters program, my programming skills are not yet at the level that I want them to be.

I recently started some work for my research assistantship concerning Twitter data for @DataONEorg.

I’m interested in the content of posts, and the relationships between the actors in the network.

In terms of content, I’d like to look at the hashtags and links.

To illustrate how difficult it is to accomplish tasks “by hand,” I recently tried to the twitter data from a free site.  My efforts are documented here: <>.

I’ve read that employers should not hire a “data scientist” if the so-called “scientist” does not have programming skills.  For this reason, I’m disappointed that the School of Information Science does not offer a programming course within the School itself.  (I’ve heard Dr. Potnis will offer a course in Fall 2014, a semester after my graduation).

I enrolled in a programming course in the College of Engineering and Computer Science – Introduction to Programming for Scientists and Engineers.  The course focuses on C++ language.  This is unfortunate, as python is increasingly favored over C++.  This means more ready-made programs are available, and a user community is growing. Content management systems are even building up around python.

Python is used by a friend of mine who does genome science.  C++ is useful for taking advantage of parallelism, but that my friend who works on supercomputers uses python suggests to me that python works as well.

Programming language popularity.

Parkridge / Magnolia Corridor / Woodbine “Neighborhood Greenway”

Something I’d like to suggest for a Magnolia corridor development plan is a Woodbine Avenue “Neighborhood greenway.”  Woodbine is a low volume residential corridor connecting Caswell Park to Chilhowee Park and the Knoxville Zoo.  There are already street signs highlighting the route.
However, there is not a direct tie-in from the Caswell Park Greenway to Woodbine, and there one dangerous crossing at the intersection of Woodbine and Cherry Street.
Neighborhood Greenways are very popular in Portland, Oregon as “residential streets with low volumes of auto traffic and low speeds where bicycle and pedestrians are given priority.”
A neighborhood greenway would be very easy to accomplish – essentially adding markings on the pavement, traffic calming to deter motor vehicle thru-traffic, clear signage, and improved crossings.
Here’s a link to Portland’s page –
Traversing historic Parkridge and Park City, Woodbine is the ideal thoroughfare for Knoxville’s first “Neighborhood Greenway” to connect   Caswell Park and the Knoxville Zoo. The PCO has already expresssed interest in making the neighborhood more accessible to cyclists – and hopes to have the Tour de Lights visit this year.  A neighborhood greenway on Woodbine ​would be a great first step to a more bike-friendly Parkridge.
