Penalized splines can be viewed as BLUPs in a mixed model framework, which allows the use of mixed model software for smoothing. Thus, software originally developed for Bayesian analysis of mixed models can be used for penalized spline regression. Bayesian inference for nonparametric models enjoys the flexibility of nonparametric models and the exact inference provided by the Bayesian inferential machinery. This paper provides a simple, yet comprehensive, set of programs for the implementation of nonparametric Bayesian analysis in WinBUGS. Good mixing properties of the MCMC chains are obtained by using low-rank thin-plate splines, while simulation times per iteration are reduced employing WinBUGS specific computational tricks.

- Adaptive Bayesian Procedures Using Random Series Priors (2014, methodology): “Although a random series with a random number of terms has been used by practitioners in various applied models [Crainiceanu et al., 2005], theoretical properties of such priors have been studies only very recently for some particular choices of bases and prior distributions on the coefficients.”
