RE: st: Multinomial Logistic - ordinal variables and Odds Ratios

[Imogen Jones <Imogen.Jones@utas.edu.au>]

Thanks Richard 

Does ologit still work with svy?

I am writing an Honours thesis so am still a beginner and my supervisor doesn't even use Stata so I'm struggling.  Thank you for your help, you probably saved me a few weeks worth of work and even some false data!

Regards

Imogen Jones
