Thanks for the quick reply and for the suggestion. I have to go deep in the response screening since I am not familiar with that.
About the correlation map, I see that in the multivariate, it accepts only numerical values and the range for correlation coefficients is between -1 and 1. In the DOE module, I can evaluate a test matrix with a correlation map that accepts all factors, including categorical, and the range for the correlation coefficients is between 0 and 1. I am wondering whether this second type of correlation map is available outside the DOE module to make analysis of correlation of data from experiments.
