Connect and share knowledge within a single location that is structured and easy to search.

Given that large parts of Europe and the U.S. are currently experiencing a second large wave of Covid-19 cases and that most European jurisdictions have reacted with more or less rigorous lockdown regulations, one wonders about the effects of these regulations on social distancing compared to the one in March/April.

You should generally not use them as a substitute for each other, and use each based on the details of particular problem you face and based on what you are interested in uncovering. << Earlier this year, we used DataRobot, a machine learning platform, to test a large number of preprocessing, imputation, and classifier combinations to predict out-of-sample performance. @BranislavCuchran Can you cite a reference for these definitions?

Now that we have established that {fixest} is capable to prepare standard errors that are identical to reghdfe it is relatively straight-forward to compare the standard errors of the other packages.
