st: Testing for parallel slopes when working with survey commands

[Gitit Kadar Satat <G.Kadar-Satat@sms.ed.ac.uk>]

I'm analysing ordinal survey data using the survey commands (in  
particular - ologit). I've tried to apply the Brant test to check for  
the "parallel slopes" assumption but stata retrieved an error message  
which stated that Brant doesn't work on ologit models with weights.
Could anyone suggest a test for parallel slopes that can be used on  
ologit models that uses survey data (that is; with survey commands)?

Many thanks in advance!
