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 purpose
