It is known that to handle rare event (1's), one undersample (0's) and
correct the logistic regression model by modifying the intercept. How
is it done in proc logistic? Is is done by hand or by changing pevent?
How about in the Enterprise Miner, it is done by changing the prior or
has it to be done by hand?
