Here's the situation. We used the same program for logistic

same version of STATA (v11, which was never updated since July '09),

standard errors, significance levels, odds-ratios and R^2, BUT we
get a
different Model Constant and Log-likelihood figures. Both figures are
larger by about a factor of five from the original run of the model in
September '09. Any ideas about what would cause these two things to be
different??
Would you mind pasting the results of both procedures into an email?
Then we may be able to spot what's happening.
