HI
I need to perform a cross-validation of a model generated by negative
binomial regression. The derivation dataset is n=757 and needs to be
cross-validated with the remaining portion (n=504). Currently the 2 sets are
in separate files. Iím not sure of the appropriate STATA 9.0 Intercooled
commands to use to perform and test the cross-validation.
I welcome any assistance you can give.
Thanks,
Cynthia
