Helmut, i have found an easy way to calculate the variance.covariance matrix:

Calcualting the matrix with this way, the result is same like excel data anaysis toolpak.

"The method dependet approaches" calculates an other result.

I hope, DDSolver calculates correct as well, but i don't know ddsolver uses some other factors as well.

Imagine if every Thursday your shoes exploded
if you tied them the usual way.
This happens to us all the time with computers,
and nobody thinks of complaining.    Jef Raskin
