i'm trying to figure out how regression using pca works in Matlab...I have standardised my variables, performed pca on them, and then done a regression on the principal components, but what is not clear to me is how I convert the regression coefficients to coefficients for my original data?! Any help would be much appreciated! Thanks

    Can you show us the MATLAB code you have so far? Concrete code from your side will make it a lot easier to get concise answers. Otherwise the answer would almost need to be a tutorial, which is not how Stack Overflow works. – WhiteViking Oct 12 '15 at 22:20
