robust standard errors? #9

Closed flh3 closed 1 year ago

flh3 commented 1 year ago

Hello,

Just wanted to confirm: are standard errors (SEs) used in mix robust SEs? The mix documentation indicates:

"the standard errors of the fixed effects, robust if robustSE was set to true"

However, there is no mention of where to set robustSE and what is the default. I am asking since at times, I would like to compare the model-based vs. robust standard errors.

Thank you.

@flh3 the standard errors on the coefficients are always CR-0 in WeMix. I agree the documentation needs to be updated.
