a blog on spatial research and data visualization in R. by paul bidanset © 2013-15


I started this blog to post about research endeavors and interests of mine both professionally and academically. The purpose of this blog is 3-fold:

1) Demonstrate the relevance and spatial statistical power (and fun!) of the R programming language

2) Teach others with a background in research and statistics how to use these R features

3) Gain feedback on my work

With this site, I’m going to continue attempting to hammer on what is actually transpiring in R, ideally without dragging my feet and stagnating the more advanced users, using an intuitive approach so readers understand not just THAT something happens, but HOW and WHY it happens. This ideally means they remember, are able to reproduce results, and ultimately grow in their learning. Your feedback is key!

I’m available for hire on specific projects (modeling, report writing, data visualization) so please feel free to email me.

If you want to learn a little about me…

My name is Paul Bidanset. I am completing a PhD with the University of Ulster in real estate valuation modeling. I also work as a modeler and statistician for a local government in southeast Virginia. In this role, I am exploring spatial and temporal modeling approaches to increase equity and uniformity of ad valorem real estate property assessments. I graduated in 2009 with a B.S. in economics from James Madison University, and received an M.A. in economics from Old Dominion University in August of 2013. My research areas of interest include: geocomputation, quantitative geography, spatial analysis, spatiotemporal methods, and mass appraisal of real estate. In my spare time I play a mean clawhammer banjo, lounge with my Weimaraner Scout, and go barefoot in the great outdoors by any and all means possible (fishing, kayaking, camping, etc.)
