%% Estimate Multivariate Kernel Density %% % Load the Hald cement data. load hald %% % The data measures the heat of hardening for 13 different cement % compositions. The predictor matrix |ingredients| contains the percent % composition for each of four cement ingredients. The response matrix % |heat| contains the heat of hardening (in cal\g) after 180 days. %% % Estimate the kernel density for the first three observations in % |ingredients|. xi = ingredients(1:3,:); f = mvksdensity(ingredients,xi,'bandwidth',0.8);
