BMDP
BMDP is a statistical package developed in 1965 by Wilfrid Dixon at the University of California, Los Angeles. Based on the older BIMED program, developed in 1960 for biomedical applications, it used keyword parameters in the input instead of fixed-format cards, so the letter P was added to the letters BMD, although the name was later defined as being an backronym for Biomedical Package.
BMDP was originally distributed for free. It is now offered by Statistical Solutions.
