You have to think about a loop. The analogy with jackknifing here is far too tenuous to be pertinent to your programming.

But before you think about a loop, have you done the combinatorics here? For 10 provinces, I count about 1000 regressions, and naturally they are highly dependent.

I have a question about delete k jackknife estimation. However, I would like to delete k groups at a time, rather than k observations.

Basically I want to run a regression of the type:

reg y  i.province othercontrols

I then want to leave out all combinations of 1 province (with a dataset saving coefficients). Then I want to leave out all combinations of 2 provinces, all combinations of 3 provinces, etc

Up to this point, all that I see would be possible is all combinations of deleting 1 observation at a time, or deleting 1 cluster at a time. I could define province as my cluster, but this will still only leave out one at a time. Other than writing a loop, is there any way that you know of how I could use the jackknife command to achieve this.
