Unexpected error "r(101)" when combining melogit with if-statement

[Adriaan Hoogendoorn]

Dear All,

I get an unexpected error "if not allowed, r(101);"when I combine melogit with the if statement as in:

webuse bangladesh
melogit c_use urban age child* || district: if district<50

I am using Stata 15.0, Update level 25 Sep 2017 on Windows 10 and guess it is a bug.

Kind regards, Adriaan Hoogendoorn

It runs when you type

melogit c_use urban age child* if district<50 || district:

This is consistent with the syntax diagram in the help file of melogit: there is a fe_equation that appears before specifying the nesting structure (the || ), and if and in are specified in the fe_equation, i.e. before the ||.

Thanks Maarten, for helping me out!
I guess my confusion came from other Stata commands (mixed, meqrlogit) that allowed for the alternative ordering.
Cheers, Adriaan
