The EnvironmentalStats module for S-PLUS has capabilities for estimating
parameters from a wide variety of distributions, using methods including MLE
and Method of Moments. For example, it adds a function "enorm" (e is for
"estimate") to dnorm, rnorm, etc., and similar functions for other
distributions in S-PLUS and more besides.
Despite the name, EnvironmentalStats is useful in just about all areas of
statistics.
