I found out that my panel data 'suffers' from heteroscedasticity by doing the test described on Stata FAQ, Testing for panel-level heteroskedasticity and autocorrelation. I understand that the $H_0$ for lrtest
is homoskedasticity and I'm rejecting this. Please correct me if I'm wrong here.
I'm carrying out a fixed effects logistic regression with xtlogit
and I found that the vce
option should be used to correct for heteroskedasticity. Still, I don't understand when to use vce(bootstrap)
or vce(jackknife)
?
What's the difference between the two? How can I decide which one to use?
EDIT: Some info on the data size:
Number of observations: 116304
Number of groups 2549
Obs per group: min = 1
avg = 45.6273
max = 20
