Includes regressors that are not specified in regressor_order. print summary_col([m1,m2,m3,m4]) This returns a Summary object that has 55 rows (52 for the two fixed effects + the intercept + exogenous D and E terms). Statsmodels also provides a formulaic interface that will be familiar to users of R. Note that this requires the use of a different api to statsmodels, and the class is now called ols rather than OLS.
