factor analysis backwards
Hello!
How can I do a factor analysis backwards to get an arbitrary covarianz
matrix out of an arbitrary number of generated random variables that
have a correlation near zero. Or the same question shorter: How to
generate random variables that have a spezial correlation pattern.
I would like to be able to do this to generate arbitrary data structures
for simulation purp...
