Hi!

I am absolutely new to STATA and I hope that you could help me to solve this issue.

I run a logistic regression on the survey data:

svy: logistic f30_b_grupp i.f17_d i.f2_grupp i.f20_grupp i.f4_grupp i.fodland_grupp

But when I try to estimate the goodness of fit with svylogoitgof, I get the following mistake:


. svylogitgof
�lder invalid name
r(198);


I tried to google but it did not help. There is no a varaible ålder in the data set.

I will appreciate any help.

Thank you in advance.

Best regards,
Yuliya
