Dear all!
Does somebody have an experience with estimating the covariance matrix of
theta_hat where theta_hat is a vector of estimators regarding lattice
data. I would like to use resampling of subregions of the lattice (say, if
my original grid is 20X20, I would like to evaluate some statistics on all
overlappings of size 10X10).
Does somebody have an idea of S function to make such resampling
efficiently? I have C code to calculate the statistics but resampling is
a problem.
Thank you in advice for any helpful suggestions.
Viki.
