%% Normal Probability Plot of Linear Model Residuals % Create a normal probability plot of the residuals of a fitted linear model. %% % Load the |carsmall| data and fit a linear model of the mileage as a % function of model year, weight, and weight squared. %% load carsmall X = [Weight,Model_Year]; mdl = fitlm(X,MPG,... 'y ~ x2 + x1^2','Categorical',2); %% % Create a normal probability plot of the residuals of the fitted model. plotResiduals(mdl,'probability')
