Question

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!

Was it helpful?

Solution

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

Anova helper functions and examples for ANCOVA interactions http://statsmodels.sourceforge.net/devel/examples/generated/example_interactions.html

using formulas to create the design matrix http://statsmodels.sourceforge.net/devel/example_formulas.html

the core OLS model http://statsmodels.sourceforge.net/devel/generated/statsmodels.regression.linear_model.OLS.html
