%% Leverage Plot of Linear Model % Plot the leverage values of observations in a fitted 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 tbl = table(MPG,Weight); tbl.Year = categorical(Model_Year); mdl = fitlm(tbl,'MPG ~ Year + Weight^2'); %% % Plot the leverage values. plotDiagnostics(mdl) %% % Plot the Cook's distance. plotDiagnostics(mdl,'cookd') %% % The two diagnostic plots give different results.
