Ich habe in R eine Version von SIR gefunden und ausprobiert. Leider kann diese multivariate Responses nicht verarbeiten. Gibt es in R eine ausgefeilte Version von SIR?

I have found a version of SIR in R and I have tried it. But the problem with this file is the fact that it does not cope with multivariate response variables. Is there any version of SIR available that also works with multivariate responses? Thanks for help!
SIR and other dimension reduction methods are available in the "dr" package on CRAN. (No idea if that's what Vera was referring to.) From a quick glance, I don't think it handles multivariate responses. Cheers, Andy> From: Uwe Ligges > > Vera Hofer wrote: > > > Ich habe in R eine Version von SIR gefunden und > ausprobiert.

This is strange; the sir for R I know (in package dr on CRAN, from S. Weisberg), last time I checked (about a year ago?) was able to handle multivariate responses. In fact, p. 6 of the documentation shows an example of SIR with a bivariate response, and I tried it, and it works. Best, R.
