Bio

I am currently an educational/statistical consultant for SPSS, an IBM Co. I am an IBM Certified trainer in SPSS and Modeler and teach SPSS and Modeler classes part-time for IBM. I retired from IRS in Dec. 2007, after 32 years with the U.S. Federal Government. I also did 2 overseas assignments for the IMF in Greece and China.

I am currently an educational/statistical consultant for SPSS, an IBM Co. I am an IBM Certified trainer in SPSS and Modeler and teach SPSS and Modeler classes part-time for IBM. I retired from IRS in Dec. 2007, after 32 years with the U.S. Federal Government. I also did 2 overseas assignments for the IMF in Greece and China.

At IRS, I was known as “Mr. DIF” because of my leadership, oversight, and hands-on development of IRS’ discriminant function (DIF) statistical models for selecting all types of tax compliance workload. At IRS, I also accumulated extensive experience in: 1) other case selection and resource allocation modeling using regression and decision tree (CHAID, CART, & C5.0) methods; 2) tax gap and tax compliance research analysis and economic modeling; 3) business measures development, monitoring, and analysis; 4) sample survey design and analysis; and, 5) customer satisfaction survey design and market segment analysis.

I have exceptional leadership, project management, and statistical analysis and modeling skills, and I am very proficient in IBM SPSS (using it for statistical analysis and modeling) and Modeler software (using it for statistical analysis and modeling and for text and data mining). I am also proficient in Microsoft Word, Excel, PowerPoint and Visual Basic.

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.

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.

Incredibly Knowledgeable, Experienced and Thorough Tutor

Donald was so kind even though I had a mishap with my time zone and some strange technical errors during the lesson but he was very patient. He went through the entire assignment with me and thoroughly explained what everything meant and even went over different ways of using SPSS. I appreciate all of his help and would recommend him to anyone needing SPSS or biostats assistance!

Donald is an excellent tutor!

Donald assisted me with my homework assignment using SPSS to analyze 3 different data files. We worked with 3 different SPSS procedures: 1) Descriptive Statistics...Frequencies; 2) Descriptive Statistics...Descriptives; and, 3) Data...Select Cases. We produced frequency tables, selected summary statistics, and histograms and bar charts for various variables. Donald is an excellent and patient instructor that I highly recommend. I will definitely use his tutoring services again!

Dummy variables for SPSS

Donald showed me a much easier way to enter dummy variables. And then I was able to demonstrate it back. Very relieved that I can proceed with my statistics homework!

Knowledgeable

Don was so great! He really helped me with my assignment. I will definitely call on him before the semester is over! Initially I couldn’t meet at his suggested time. When I told him what day I would be available he offered a different time. I am so appreciative of his help!
