Hi All,
I am little confused understanding the PCA plot generated from JMP. In the plot below, products in the top-right quadrant are correlated positively, i.e. if one of them increases, all other increase ('am I right ?). What about the products in the lower-right quadrant and the upper left quadrant.
Thanks for your help
Cheers
