May 2, 2012 - Abstract. We propose a new data-augmentation strategy for fully Bayesian inference in models with logistic likelihoods. To illustrate the method we focus on four examples: binary logistic regression; contingency tables with fixed margin

Latent force models (LFMs) are hybrid mod- els combining mechanistic principles with non-parametric components. In this article, we shall show how LFMs can be equivalently formulated and solved using the state vari- able approach. We shall also show
