Bootstrap sample

Hell,

I am using Maxboot to compute the bootstrapped estimates of parameters of a maximum likelihood function, but I want to retrieve all the random samples that were used to compute these estimates.

Any help would be appreciated.

Thanks.

Sincerely,

Sajjadur.

With some programming it would only be possible to retrieve the number of times each observation occurred in the re-sampling.

If it is important to look at each sample in the re-sampling, put the call to Maxlik in a loop and generate the bootstrap samples yourself using the GAUSS function exctsmpl():

x0 = {};

for I(1,100,1);

subsample = exctsmpl("originalData","newData",100);

{ x,f,g,cov,ret } = maxlik("newData",0,&lpr,x0);

if ret == 0;

x0 = x0 | x';

endif;

endfor;

print "bootstrap estimate";

print meanc(x0);

print "standard errors";

print sqrt(diag(varcovx(x0)));
