I'd like to fit binomial or multinomial logistic regression models using the method of fractional polynomials. Does IBM SPSS Statistics have a procedure that automates this process?
Resolving The Problem
No, IBM SPSS Statistics currently does not offer automatic fitting of models using fractional polynomials. You may want to consider the R package mfp, which may be accessed from within IBM SPSS Statistics via the R plug-in, available from developerWorks (https://www.ibm.com/developerworks/mydeveloperworks/groups/service/html/communityview?communityUuid=ab16c38e-2f7b-4912-a47e-85682d124d32) or on your installation media
