Please note that some Anti-Virus programs and sometimes Windows itself will recommend that you do not download these programs or block you from downloading or running them. You can usually bypass this block by clicking more information and then choosing to download or run anyway. I use both Norton Anti-Virus and Kaspersky on different computers I use to compile these programs. Neither program has ever complained while I compile the programs. I have even had situations where Norton stopped me from downloading one of my own programs that I just uploaded even though I just compiled it on that same computer with Norton active… They just don't seem to like relatively new programs that don't have many users.

 

Available Software

·       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.

·       Most of the documents available with the programs (e.g., user guides, instructor guides, lesson plans, student exercises) are in Adobe Acrobat PDF format. If you need the Adobe Reader, you can download it from their web site free.

 

BMA: Basic Matrix Algebra (for Statistics)

BMA is a Windows 9x/NT/2000/XP/7 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. The current version will be presented at the 2003 meeting of the Mid-Western Educational Research Association in Columbus, IL. 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/7 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. Although some AUXILIARY MATERIALS may have been created for use with a previous version of the program, they should still be very useful with newer versions of the program; that is, changes to the program usually are not dramatic enough to make earlier manuals obsolete. An article about FISH was published in Teaching Statistics and FISH was most recently presented at the annual meeting of the Joint Statistical Meetings, August 2004, Toronto, Canada.

HMF : Harmonic Mean Finder

HMF is a little Windows 9x/NT/2000/XP/7 program written in Delphi Pascal that calculates the Harmonic Mean in a variety of ways (particularly useful for Power and Sample Size analyses). It will calculate (a) the harmonic mean, (b) the sample size needed for group 2 for a given group 1 sample size and desired harmonic mean, (c) several combinations of sample sizes that result in the given harmonic mean, and (d) the harmonic mean for 3-6 groups.

MC2G: Monte Carlo Analyses for 1 or 2 Groups

MC2G is a Windows 9x/NT/2000/XP/7 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 (or correlations are zero) and power analyses when the means are not equal (or correlations are non-zero). 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, and 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/7 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 was most recently presented at the annual meeting of the American Educational Research Association, April 2002, New Orleans, LA.

MC4G: Monte Carlo Analyses for up to 4 Groups

MC4G is a Windows 9x/NT/2000/XP/7 program written in Delphi Pascal that runs Monte Carlo simulations for One-Way ANOVA (with 2, 3, or 4 levels). 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. It can also be used to estimate required sample sizes. 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, and an article about MC4G is in press to be published in 2005 in Teaching of Psychology.

MCCM: Monte Carlo Correlation Matrices

MCCM is a Windows 9x/NT/2000/XP/7 program written in Delphi Pascal that performs Monte Carlo analyses for several bivariate correlations simultaneously, particularly useful to show the effect on Type I error (or power) when testing several bivariate correlations all at alpha of .05. That is, it will generate data to illustrate the effect on Type I error of running multiple bivariate correlations simultaneously. The user can specify item means and standard deviations as well as correlations.

MCMR: Monte Carlo for Multiple Regression

MCMR is a Windows 9x/NT/2000/XP/Vista/7 program written in Delphi Pascal that performs Monte Carlo analyses for Multiple Linear Regression with up to 6 predictors. The user must specify means and standard deviations as well as correlations, but can also import a single file for analysis. MCMR was most recently presented at the annual meeting of the American Educational Research Association, March 2008, New York, NY, and an article about MCMR was in Multiple Linear Regression Viewpoints (www.glmj.org/).

TAP: Test Analysis Program

TAP is a Windows 9x/NT/2000/XP/7 program written in Delphi Pascal that performs test analyses and item analyses based on classical test theory. TAP is a classical test and item analysis program. It provides reports for examinee total scores, item statistics (e.g., item difficulty, item discrimination, point-biserial), options analyses, and other useful information. TAP also provides individual examinee reports of total scores and item responses. Although any AUXILIARY MATERIALS may have been created for use with a previous version of the program, they should still be very useful with newer versions of the program; that is, changes to the program usually are not dramatic enough to make earlier manuals obsolete. TAP was most recently presented at the annual meeting of the American Psychological Society, May 2004, Chicago, IL, and a program announcement for TAP was published in 2003 in Applied Psychological Measurement.
