Aspects of smoothing and model inadequacy in generalized regression

Abstract We present a Bayesian semiparametric approach to exponential family regression that extends the class of generalized linear regression models. Further, flexibility in the process of modelling is achieved by explicitly accounting for the discrepancy between the ‘true’ response-covariate regression surface and an assumed parametric functional relationship. An approximate full Bayesian analysis is provided, based upon the Gibbs sampling algorithm.
