pf.summary()
pf.etable()
With #556 , @Jayhyung has implemented support for the effective F statistics (Olea & Pflueger) as well as a "standard" first stage F test.
We should include these statistics by default in the output produced by pf.summary and pf.etable.
pf.summary
pf.etable
For example, r-fixest returns the following information:
r-fixest
library("fixest") data("SchoolingReturns", package = "ivreg") m_iv <- feols(log(wage) ~ ethnicity + smsa + south | education ~ nearcollege , data = SchoolingReturns) summary(m_iv) # TSLS estimation, Dep.

Include information on the first stage f statistics and effective f statistic to pf.summary() and pf.etable().
The text was updated successfully, but these errors were encountered:
Something else that could be cool: adding an include_first_stage argument so that instead of having to type
include_first_stage
%load_ext autoreload %autoreload 2 import pyfixest as pf data = pf.get_data() fit = pf.feols("Y ~ X2 + f2 | X1 ~ Z1", data = data, vcov = "iid") pf.etable([fit._model_1st_stage, fit])
users could just call
%load_ext autoreload %autoreload 2 import pyfixest as pf data = pf.get_data() fit = pf.feols("Y ~ X2 + f2 | X1 ~ Z1", data = data, vcov = "iid") pf.etable([fit], include_first_stage)
and get identical output.
Sorry, something went wrong.
