I don't use SPSS but you should check which variables are regarded as string by Stata. -describe- or -varm- will tell you this. You may need to -encode- or -destring- some variables.

I have recently migrated from SPSS to Stata to allow me to implement
fractional polynomial techniques, including the mfp procure, for a
logistic regression analysis. I have been able to save the original SPSS
file in Stata format. The variables in the SPSS file were of numeric
"Type" (in the sense intended by the SPSS Variable View facility) with
text labels linked to the numerical codes using the SPSS Value Labels
function. On opening up the Stata version of this file, the text labels
appear in the individual columns for the dependent and independent
variables. When I run the code for identifying the Stata file and
running the mfp procedure, the error code r(2000) is generated, pointed
to an absence of observations.
Is it possible that I require to reformat the data in some way for the
procedure to run successfully?
