Set Up Multivariate Regression Problems

To fit a multivariate linear regression model using mvregress, you must set up your response matrix and design matrices in a particular way.

Multivariate General Linear Model

This example shows how to set up a multivariate general linear model for estimation using mvregress.

Fixed Effects Panel Model with Concurrent Correlation

This example shows how to perform panel data analysis using mvregress.

Longitudinal Analysis

This example shows how to perform longitudinal analysis using mvregress.

Partial Least Squares Regression and Principal Components Regression

Apply partial least squares regression (PLSR) and principal components regression (PCR), and explore the effectiveness of the two methods.

Conceptos

Multivariate Linear Regression

Large, high-dimensional data sets are common in the modern era of computer-based instrumentation and electronic data storage.

Estimation of Multivariate Regression Models

When you fit multivariate linear regression models using mvregress, you can use the optional name-value pair 'algorithm','cwls' to choose least squares estimation.

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.
