Dear community,
I/m trying to understand the differences behind the boottest and cgmwildboot commands...maybe a first question is, ...should the boottest and cgmwildboot command give the same results? (using the same seeds and regression). I find that the results are different (although they are closer between each other than with the non-bootstrapped errors).
Below the example using the nlsw88 data like in the cgmwildboot help file.
set seed 293867483
webuse nlsw88, clear
drop if industry==. | tenure==.
regress wage tenure , cluster(industry)
boottest {tenure} , cluster(industry) rep(1000) seed(12345) nograph boottype(wild) bootcluster(industry)
cgmwildboot wage tenure, cluster(industry) seed(12345) reps(1000) bootcluster(industry)
In the case of the cgmwildboot the CI for tenure is [.13334021 .23370585], while when using boottest the CI for tenure is [.1250953 .2410478].
It is also not a matter of number of reps.
thansk for any help!
