I am running Proc Logoctics procedure.I got the message "Ridgin failed to improve the likelihood function". I changed the option ridging = absolute and this also gave the same message.
With Ridging = none , the no. of iteration increased , but still the model ended with same warnning . This time the message was to use halfmax=option and increase no. of steps oe specify a new set of initial parameter estimates using INEST option. What does this mean?.
I have 26 predictor variables in the model , is this because of large no. of variables. If so then how do we reduce the variables.
