Hi,
I'm doing an analysis calling the pls_analysis.m command and now that I have the result structure as output, I was hoping to find the percent crossblock covariance accounted for over the different LVs. I can't seem to locate where that is specifically, so could anyone tell me where I might look for this, or if its not reported in the result structure, how might I compute this myself?
Thanks,
Mike

hmm - seems we forgot to include it. Its a simple calculation though, its the ratio of the squared singular value over the sum of the squared singular value:
In pls_analysis:
result.s.^2/sum(result.s.^2)

Hi Randy,
Great, thanks very much! A very helpful line of code.
