R help - Dec 2000 - sm library

Hello to everyone

Does someone know where is the bug in sm.logit function in sm library?

The estimated probabilities are always 1/2

I'm new to this list, so I don't know if this list is about this kind of
things.

Sorry for my english, and thanks in advance

Oscar

Please look in the archives, as I posted the solution a day or so ago.
The bug is that glm.fit has been broken since that function was ported to
R, and now gives linear predictor 0 for weight-zero cases, incorrectly.

The best solution is to get the new sm2 package, on its way to CRAN now.
You can pick up a version from
http://www.stats.ox.ac.uk/pub/R/sm_2.0-1.tar.gz or a Windows port at
http://www.stats.ox.ac.uk/pub/RWin/sm.zip (for rw1020), both as from about
five minutes ago.
