PROC CALIS may do this, but it is not something I could help with. Also, within the Partial Least Squares methodology, there are indeed multi-block models, I would imagine that this could be extended from multi-block PLS to multi-block PCA. I know the lead author Age Smilde has done a lot of work in this area, maybe you should contact him directly.

Correlation comes from transforming variables to have mean=0 and variance=1. Covariance has mean=0, but no transformation of the variance is done.

Hi, I think this paper is better to use: https://www.pharmasug.org/proceedings/2018/DV/PharmaSUG-2018-DV20.pdf But, first your dataset needs to be arranged to show which observations are in each of the groups. Please look at the VennData dataset to see how the Dataset should be arranged. But as a quick example, your dataset create a dataset that has 3 variables, such as WBC, RBC and AT. And if one of the records each has WBC, RBC and AT, then all the columns would have the same value.
