Copy Code Copy Command Load the examgrades data set. Get load examgrades Use the last exam scores as response data and the first two exam scores as predictor data. Get y = grades(:,5); X = [ones(size(grades(:,1))) grades(:,1:2)]; Perform multiple linear regression with alpha...
This MATLAB function returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X.
Section 3.02.5 contains the simple MATLAB18 code that can be used for calculating some of the diagnostics presented in this text. The appendices contain extended information about OLS regression and the singular value decomposition (SVD). View chapter Reference work 2009, Comprehensive ChemometricsJ....
