%% Fit Linear Model Using Default Confidence Intervals % Fit a linear regression model for auto mileage based on the |carbig| data. Then % obtain the default 95% confidence intervals for the resulting model coefficients. %% % Load the data and create a table. load carbig Origin = nominal(Origin); tbl = table(Horsepower,Weight,MPG,Origin); %% % Fit a linear regression model. Use horsepower, weight, and origin as % predictor variables, and miles per gallon as the response variable. modelspec = 'MPG ~ 1 + Horsepower + Weight + Origin'; mdl = fitlm(tbl,modelspec); %% % View the names of the coefficients. mdl.CoefficientNames %% % Find confidence intervals for the coefficients of the model. ci = coefCI(mdl)
