Hi everyone,

we would like to run a power calculation for beta-coefficients / odds ratios in logistic regression models with covariates.
Is such a procedure implemented in SATA?

Used command for the logistic regression model:
svy: logit depression age sex comorbidity, or

Data stems from a national representative survey. Dependent variable is depression. Comorbidity is dichotomised. Now, we are interested in the "post hoc" power of the odds ratio of comorbidity.

Can anybody give us some advice, please? Thanks in advance!
