Statistics

My degree is in Statistics and I spent 32 years at IRS conducting various research projects---10 years as a mathematical statistician and 22 years as a research manager. My expertise is in 2 areas: 1) statistical analysis (from simple stats like averages, confidence intervals, & t-tests to more complex stats like ANOVA & factor and cluster analysis); and, 2) statistical modeling (primarily regression and discriminant analysis). Currently, as an independent contractor, I teach statistical analysis and modeling and data mining for IBM.


SPSS

My degree is in Statistics and I spent 32 years at IRS conducting various research projects---10 years as a mathematical statistician and 22 years as a research manager. Currently, as an independent contractor, I teach SPSS and Modeler for IBM. I teach 22 different classes, ranging from simply how to use the SPSS and the Modeler software to how to use SPSS to conduct complex statistical analysis and modeling and how to use the Modeler software to do data mining and text mining. I have been teaching these subjects since June 2008, after I retired from IRS.


Biostatistics

Since June 2008, I have been teaching numerous advanced statistical analysis classes for IBM, including the class entitled Advanced Statistical Methods for Healthcare Research. This particular class covers many biostatistical methods such multi-way and multivariate ANOVA, linear & logistic regression, discriminant analysis, and t-tests. In addition, I have been tutoring many students in advanced statistical research and analysis---consistently receiving the highest ratings.
