Revised sources for "alr" (alternating logistic regression)
for Splus have been posted at


This revision corrects a bug (numerically undetectable in
a number of applications examined thus far, and inferentially
innocuous in all applications examined thus far) apparently
emanating from obsolete f2c translation of linpack/blas
routines. Notes on the bug are provided at the aforementioned web
site. The revision also modifies the definition of the
pairwise log odds ratio regression design matrix and includes
a compatible version of "class2z", a pairwise log odds ratio
regression design matrix generator developed by P. Heagerty
of U. Washington.
