Fitstat gives error message

Hi all,

When I use fitstat after a ologit regression, I get this message:

Code:

. fitstat

Measures of Fit for ologit of A1

variable _cons not found
r(111);

My full output is this:

Code:

. ologit A1 i.G1 i.SQ3_2_1 i.SQ3_3_range_1 i.SQ3_4_1 i.SQ3_7_1 i.SQ4 i.BA2, nolog

Am I doing something wrong?

Thanks in advance.
