This technique, also known as (maximum) redundancy analysis, differs from multivariate linear regression only when there are multiple responses. partial least squares regression, which balances the two objectives of explaining response variation and explaining predictor variation. Two different formulations ...

I have a multivariate model, Y ~ X1 + X2 + X3 + X4 + X5 + X6 + intercept(?) I read that it is better to keep the intercept else the regession line will be biased especially it is forced to go through the origin with 6 variables in the equation above. However, in the...
Other helpful guidelines and discussions cover the following significant areas: Multivariate linear models; lack-of-fit analysis; covariance and heterogeneity of slopes; a classification with both crossed and nested effects; and analysis of variance for balanced data. This fourth edition includes updated...
