Please note that all my software is constantly under development.  I do my best to verify the code and the algorithms; but unfortunately, I can test the software only so much by myself (or even with help from a few colleagues and students).  Please contact me if you find bugs or errors and I will do my best to fix them quickly.  I also welcome any suggestions you might have to improve the programs (or even new programming ideas).  Of course, this also means that if you find something you like, you should check back occasionally to see if there is a new upgrade available.

BMA: Basic Matrix Algebra (for Statistics)

BMA is a Windows 9x/NT/2000/XP program written in Delphi Pascal that performs matrix manipulations.  It is designed for use in advanced statistics courses where a conceptual understanding of matrix algebra is desired without much calculation by hand.  It takes the user step-by-step through several matrix algebra functions, including addition, multiplication, transposition, and inversion. 

BMA was most recently presented at the annual meeting of the Mid-Western Educational Research Association, October 2003, Columbus, OH:

FISH: Friendly Introductory Statistics Help

FISH is a Windows 9x/NT/2000/XP program written in Delphi Pascal that performs introductory descriptive and correlation analyses.  It is intended to be used as a supplement to introductory statistics courses.  It is designed for use in basic statistics courses where a conceptual understanding of statistics is desired without much calculation by hand.  It takes the user step-by-step through the calculation of means, standard deviations, z-scores, and correlations.

FISH was most recently presented at the annual meeting of the Joint Statistical Meetings, August 2004, Toronto, Canada:

bulletBrooks, G. P., Raffle, H., Lewis, M., & Blom, V. (2004, August). A computer program for friendly introductory statistics help. Poster presented at the Joint Statistical Meeting (American Statistical Association), Toronto, Canada.

MC2G: Monte Carlo Analyses for 1 or 2 Groups

MC2G is a Windows 9x/NT/2000/XP program written in Delphi Pascal that runs Monte Carlo simulations for several single sample and two-sample tests:  Independent t, Dependent t, Single-sample t, Mann-Whitney-Wilcoxon, Wilcoxon Signed Rank, Pearson Correlation, Spearman Rank-Order Correlation.  By providing the total number of rejections at the user-specified level of significance, MC2G performs robustness analyses when means are equal and power analyses when the means are not equal.  The original purpose of the program was to assist in the instruction of power analysis and violations of assumptions for introductory educational statistics courses.  However, with a little effort the program can be used to answer actual Monte Carlo research questions. 

MC2G was most recently presented at the annual meeting of the Mid-Western Educational Research Association, October 2003, Columbus, OH:

bulletBrooks, G. P., Abdulla, A., Al-Harbi, K., Kanyongo, G., Kyei-Blankson, L., & Gocmen, G. (2002, April). Teaching introductory statistics with the help of Monte Carlo methods. Paper presented at the meeting of the American Educational Research Association, New Orleans, LA.

A program announcement and example lesson plans for MC2G was published in 2003 in Understanding Statistics:

MC3G: Monte Carlo Analyses for 3 Groups

MC3G is a Windows 9x/NT/2000/XP program written in Delphi Pascal that runs Monte Carlo simulations for 3-level ANOVA. By providing the total number of rejections at the user-specified level of significance, MC3G performs robustness analyses when means are equal and power analyses when the means are not equal.  The original purpose of the program was to assist in the instruction of power analysis and violations of assumptions for introductory educational statistics courses.  However, with a little effort the program can be used to answer actual Monte Carlo research questions. 

MC3G has essentially been replaced by MC4G (see below).

MC4G: Monte Carlo Analyses for up to 4 Groups

MC4G is a Windows 9x/NT/2000/XP program written in Delphi Pascal that runs Monte Carlo simulations for up to 4-level ANOVA. By providing the total number of rejections at the user-specified level of significance, MC4G performs robustness analyses when means are equal and power analyses when the means are not equal.  Its initial purpose was to illustrate a variety of Type I Error problems associated with ANOVA (e.g., violations of assumptions, compared to multiple t tests, probability of at least one Type I Error from multiple orthogonal tests). 

MC4G was most recently presented at the annual meeting of the American Psychological Society, May 2004, Chicago, IL:

bulletBrooks, G. P., & Raffle, H. (2004, May). Using Monte Carlo software for ANOVA to teach abstract statistical concepts. Paper presented as a Teaching Institute poster at the meeting of the American Psychological Society, Chicago, IL.
