Power calculation for mutinomial logistic regression

[John Havens]

Hi,
I try to calculate power for multinomial logistic regression (3 levels) in Stata but haven't found any command that serves that purpose. The user-written command -powerlog- can be used to calculate power for binary logistic regression, but I'm not sure if I can modify it for a multinomial logistic regression.
Thanks,
John

You can always approach power analysis with simulation. See this Stata article and this Stata FAQ.

Thank you Joseph!
