RSiteSearch("simulate specified covariance") will bring you to mvrnorm() in
MASS. Please try to use R's built-in search capabilities first before
posting. I realize that keywords can be hard to guess, but you may find that
when the hits are **not** what you want, you need to refine your question
more, as described in the posting guide (have you read it?)-- Bert Gunter -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stefan Premke Sent: Wednesday, April 12, 2006 6:52 AM To: [email protected] Subject: [R] 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 purpose sincerely stefan ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
