Could anyone please help in providing an example showing how ANCOVA (analysis of covariance) can be done in scipy/statsmodel, with python?
I am not sure if I am asking too much, but a quick search showed me this which is not informative enough for me.
Thanks!
Statsmodels uses the linear model, OLS, to estimate ANOVA. So, having additional continuous regressors as in ANCOVA does not change the analysis.
Here are a few links to the relevant documentation
