How many data clusters are in the Galaxy data set? Bayesian cluster analysis in action
Bettina Grün, Gertraud Malsiner-Walli, Sylvia Frühwirth-Schnatter
In model-based clustering, the Galaxy data set is often used as a benchmark data set to study the performance of different modeling approaches. Aitkin (2001) compares maximum likel…
Comparing Spike and Slab Priors for Bayesian Variable Selection
Gertraud Malsiner-Walli, Helga Wagner
An important task in building regression models is to decide which regressors should be included in the final model. In a Bayesian approach, variable selection can be performed usi…
Computational Solutions for Bayesian Inference in Mixture Models
Gilles Celeux, Kaniav Kamary, Gertraud Malsiner-Walli +2
This chapter surveys the most standard Monte Carlo methods available for simulating from a posterior distribution associated with a mixture and conducts some experiments about the…
Effect fusion using model-based clustering
Gertraud Malsiner-Walli, Daniela Pauger, Helga Wagner
In social and economic studies many of the collected variables are measured on a nominal scale, often with a large number of categories. The definition of categories is usually not…
Model-based clustering based on sparse finite Gaussian mixtures
Gertraud Malsiner-Walli, Sylvia Frühwirth-Schnatter, Bettina Grün
In the framework of Bayesian model-based clustering based on a finite mixture of Gaussian distributions, we present a joint approach to estimate the number of mixture components an…
