Cook, Marvin Johnston Their sources: C. Hastings Jr. T.L. kelly M.G. Kendall K.W. Smillies and T.H. Anstey Understanding and Learning Statistics by Computer, by Mark C. K. Yang and David H. Robinson For discrete distributions and incomplete gamma and beta functions: Mathematical Statistics with Applications, by Mendenhall, Scheaffer, and Wackerly (2nd Edition) General Consultation: James Kepner and David Robinson If you have statistics background, I hope this package is self-explanatory, just $RUN PVET . The author of this program was a student programmer here who has graduated and moved on.
