[R] goodness of fit

[ben@zoo.ufl.edu]

  The "ctest" library that comes with R may do part of what you want
(except for the Anderson Darling nonparametric tests, which I don't know
about).

library(ctest)
library(help=ctest)

...
chisq.test               Pearson's Chi-square Test for Count Data
ks.test                  Kolmogorov-Smirnov Tests
...

  You'd probably have to write your own stuff to fit distributions to your
data, although the large set of distribution-calculators in R (see the
"distribution" keyword under the HTML help) should help a lot.

  By the way, you might want to check the clock on your computer -- I
don't really think your message is that old ... (or are you avoiding Y2K
issues?)
