Multivariate Linear Regression
When you need to include more than one response variable in a regression
model, use a multivariate linear regression model. A multivariate linear
regression model expresses a
response vector as a linear combination of predictor terms plus a vector of
error terms with a multivariate normal distribution. You can use
mvregress to create a
multivariate linear regression model.
Partial least-squares (PLS) regression is a dimension reduction method
that constructs new predictor variables that are linear combinations of the
original predictor variables. To fit a PLS regression model that has
multiple response variables, use
A multivariate linear regression model is different from a
multiple linear regression model, which models a univariate
continuous response as a linear combination of exogenous terms plus
an independent and identically distributed error term. To fit a
multiple linear regression model, use

- Partial Least Squares
Partial least squares (PLS) constructs new predictor variables as linear combinations of the original predictor variables, while considering the observed response values, leading to a parsimonious model with reliable predictive power.
