We discuss inference for additive models with random scaling factors. The additive effects are of the form (1+?)f(z) where f is a nonlinear function of the continuous covariate z modeled by P(enalized)-splines and 1 + ? is a random scaling factor. Ad

Accommodating heterogeneity and nonlinearity in price effects for predicting brand sales and profits

We propose a hierarchical Bayesian semiparametric approach to account simultaneously for heterogeneity and functional flexibility in store sales models. To estimate own- and cross-price response flexibly, a Bayesian version of P-splines is used. Hete

Models with structured additive predictor provide a very broad and rich framework for complex regression modeling. They can deal simultaneously with nonlinear covariate effects and time trends, unit- or cluster-specific heterogeneity, spatial heterog

This paper is motivated by two common challenges in hedonic price modeling: nonlinear price functions, which require flexible modeling approaches, and the inherent spatial heterogeneity in real estate markets. We apply additive mixed regression model
