Exact Logistic Regression

I have read that exact LR should be used for rare events data since ML LR does not give correct results in rare events data. Is it possible to do Exact LR in JMP? If so, is it only limited to small number of samples?

Hi Ranjan,

There are no exact statistics in JMP.

JMP Pro has exact statistics for oneway anova and contingency tables, but not logistic regression.

reminded me that JMP does have one exact test.

In the case of a 2-by-2 contingency table only JMP does offer Fisher's Exact Test.

JMP Pro offers Fisher's Exact for any r by c contingency table.
