Hi,

I use data from complex surveys that are distributed with bootstrap weights (actually, mean bootstrap weights, but this is not the issue). 

In need to compute a variance matrix based on the deviation from the averaged bootstrap coefficients. Given that I do not know the averaged coefficients until I have performed all the relevant replications, I cannot accumulate variance. Thus I need to store the elements of the numerous e(b) somewhere until I process them with -bstat- or something similar.

The number of elements of e(b) as well as the column names differ for each analysis.

The number of covariates may reach a few dozens and the number of replications may reach 1000. Given the size, appending each e(b) in a matrix does not seem to be a workable solution.

-post- requires expressions enclosed in parentheses. I can extract the column names from e(b), but I cannot see how to turn the content of e(b) into anything palatable for -post-.

Anyone has an idea? Am I missing something obvious?

Thanks in advance.
