What is the difference between statsmodels `.summary()` and `.summary2()` function?

Question

Hey I am wondering what the differences between statsmodels .summary() and .summary2() functions are and which to use? I am curious if it is easier to read out parameter confidence intervals with .summary2()?

If this quesstion has already been asked I could not find it but would be happy for link provision redirecting me to the topic.

Answer 1

The summary2 function, as the documentation states is experimental for now https://www.statsmodels.org/dev/generated/statsmodels.regression.linear_model.RegressionResults.summary2.html.

It differs from the main summary function by yname parameter having default value and allowing it to have optional values, having float_format parameter, not having slim parameter, alpha parameter having optional values.
