# Multivariate Linear Regression

This is similar to linear regression but instead of having single dependent variable Y, we have multiple output variables. It may be written as,

Y = XB + U ,

where Y is a matrix with series of multivariate measurements (each column being a set of measurements on one of the dependent variables), X is a matrix of observations on independent variables that might be a design matrix (each column being a set of observations on one of the independent variables), B is a matrix containing parameters that are usually to be estimated. U is the regularisation factor.

Representing it in the old form,
