Projects

1. • Project: Statistical analysis of Baltimore storm water monitoring data
   • Client: Dr.Upal Ghosh, Katie DiBlasi, Department of Civil and Environmental Engineering, UMBC
   • Consultants: Dr.Neerchal and Yan Zhuang
   • Description: Provided consultation and assistance with analyzing a panel dataset in order to explore the influence of Heritage foundation EProvided statistical support for the analysis of storm wter monitoring data to elucidate the effect of street sweeping on storm water quality. Developed a method to substitute below detection limit valuesconomic Freedom indices on the inflow of foreign direct investment in developing countries.
2. • Project: Estimating land cover and land use using nonlinear regression model
   • Client: Dr.Erle Ellis, Department of Geography & Environmental Systems, UMBC
   • Consultants: Dr.Neerchal and Yan Zhuang
   • Description: A prediction model was built fro predicting land cover and land use using Bspline expansions and a technique of transforming the independent variables to capture the nonlinear relationship between the COVER(or USE) and land cover variables.
3. • Project: Statistical Analysis of Cognitive, Social and Teaching Presence in a Class Message Board
   • Client: Joan Shin, UMBC
   • Consultants: Dr. Neerchal, and Willy Weng
   • Description: Analyzed the cognitive, social and teaching Presence in a class message board to determine if: (1) There are significant differences between different semesters. (2) Measure of association exists between different variables of interest.
4. • Project: Statistical Analysis of US-Mexico Boarder Data on Ozone and PM10
   • Client: Herbert Lacayo Jr., Ph.D., U.S. Environmental Protection Agency
   • Consultants: Dr. Neerchal, Willy Weng and Mathangi Gopalakrishnan
   • Description: (AQS) database provides Ozone and PM10 data for desired degree of resolution (from hourly to annually) for various sites located in USA and its borders. Inter-site comparison, especially for sites located on either side of teh US-MExico border, is of particular interest. Since the data have both space (location fo the site) and time (measurement intervals) dimesnions. We investigate the methodolgy for performing multiple comparisons among sites, which accounts for space and time correlations.
5. • Project: Statistical analysis of larval feeding plasticity.
   • Client: Will Gretes and Dr. Jeffery Leips, Department of Biology, UMBC
   • Consultants: Justin Newcomer and Dr. Nagaraj Neerchal
   • Description: Analyzed repeated measurements of larval feeding plasticity using Generalized Estimating Equations. Presented results at the UMBC-Wyeth Summit, August 24, 2007
