Qué grande! Muchas gracias eres la primera fuente que encuentro que explica claramente como hacer una regresión de panel en python.
Don't reverse order of observation variable and time variable; if we don't have a DID specification, it is likely to be bias
Yes, don't reverse the unit of analysis variable with the time variable. I saw Ph.D. students committing this mistake several times. Some had to rewrite their dissertation after the defense because the results were all off.
Thank you
Maravilha!
Valeu Brazuca!!
When running FE in python, make sure entity_effects=True.
Or you can implement it manually with dummy variables.
