Dear all, Can anyone point me to a package that can perform Common principle components? Thank you. Jos?? P. Granadeiro
I am sorry for not being clear. I meant the methods detailed in: Flury, B. (1988). Common Principle Components Analysis and Related Multivariate Models, John Wiley and Sons, New York. (see also: http://www.quantlet.com/mdstat/scripts/mva/htmlbook/mvahtmlframe97.html). Thank you very much. Jos??

I was a lttle shocked to see your report of 3.2M hits for the correct speeling versus 1.8M for incorrect. This is a ratio of just 1.8! Google normally has much higher power than this, as the arbiter of spelling disputes. A quick google reveals however that your search is for "principal"+"components" and principle"+"components". A search for the complete strings yields a ratio of 14.8 in favour of the latter. - Giles> -----Original Message----- > From: r-help-bounces at stat.math.ethz.ch > [mailto:r-help-bounces at stat.math.ethz.ch]On Behalf Of Spencer Graves > Sent: 26 May 2004 17:25 > To: Martin Maechler > Cc: R-help at stat.math.ethz.ch > Subject: Re: [R] Common principle components > > > Google just returned "about" 1.8M hits for "principle components" and > 3.2M hits for "principal components".

A typo in previous post: for latter, read former. Apologies for the
confusion.
