| Abstract: | In the empirical study presented market share models with semi-parametric additive brand attractions attain better fits both according to an information criterion like AIC that penalizes a model for degrees of freedom used and according to error measures determined by cross validation or bootstrapping. Higher flexibility compared to strictly parametric models leads to more reliable measurements of the effects of marketing instruments. |
