Consulting Projects and Activities - Spring 2008

Projects

    • Project: Statistical Analysis of Baltimore Storm Water Monitoring Data
    • Client: Dr. Upal Ghosh and Katie DiBlasi, Department of Civil and Environmental Engineering, UMBC
    • Consultants: Dr. Neerchal and Yan Zhuang
    • Description: Provided statistical support for the analysis of storm water monitoring data to elucidate the effect of street sweeping on storm water quality. Developed a method to substitute below detection limit values.

    • Project: Estimating Land Cover and Land Use using a Nonlinear Regression Model
    • Client: Dr. Erle Ellis, Department of Geography and Environmental Systems, UMBC
    • Consultants: Dr. Neerchal and Yan Zhuang
    • Description: A prediction model was built for predicting land cover and land use using b-spline expansions and a technique of transforming the independent variables to capture the nonlinear relationship between the independent and dependent variables.

    • 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 were significant differences between different semesters. (2) Measure of association existed between different variables of interest.

    • Project: Statistical Analysis of US-Mexico Border 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: The AQS database provides ozone and PM10 data for a desired degree of resolution (from hourly to annually) for various sites located in the USA and Mexico. Inter-site comparison, especially for sites located on either side of the US-Mexico border, was of particular interest. Since the data had both space (location of the site) and time (measurement interval) dimensions, we investigated the methodology for performing multiple comparisons among sites while accounting for space and time correlations.

    • Project: Statistical Analysis of Larval Feeding Plasticity
    • Client: Will Gretes and Dr. Jeffery Leips, Department of Biological Sciences, UMBC
    • Consultants: Dr. Neerchal and Justin Newcomer
    • Description: Analyzed repeated measurements of larval feeding plasticity using Generalized Estimating Equations. Presented results at the UMBC-Wyeth Summit, August 24, 2007.
