Thank you Maggie.

What I'd like to be able to do, with things like the logistic function (any curve fitterin PDL::Stats, actually) is something like this:

my %m = $y->logistic( COV => 1 );print $m{cov}->corr_table();

I don't think logistic should return the covariance matrix by default, but I would liketo be able to get to it.

A single line patch in GLM.pm, after %ret is declared, around line 2000 or so..

$ret{cov} = $cov if ( $opt{COV} );

would do the trick for logistic, I believe. I don't think $cov is out of scope by that point.

Sincerely,

David Myers.
