Bayesian Computation in Dynamic Latent Factor Models

2 code implementations9 Jul 2020 Isaac Lavine, Andrew Cron, Mike West

Bayesian computation for filtering and forecasting analysis is developed for a broad class of dynamic models.

Adaptive Variable Selection for Sequential Prediction in Multivariate Dynamic Models

1 code implementation15 Jun 2019 Isaac Lavine, Michael Lindon, Mike West

The adaptivity allows for changes in the sets of favored models over time, and is guided by the specific forecasting goals.

Probabilistic forecasting of heterogeneous consumer transaction-sales time series

2 code implementations14 Aug 2018 Lindsay R. Berry, Paul Helman, Mike West

With a focus on multi-step ahead forecasting of daily sales of many supermarket items, we adapt dynamic count mixture models to forecast individual customer transactions, and introduce novel dynamic binary cascade models for predicting counts of items per transaction.

Bayesian forecasting of many count-valued time series

2 code implementations14 May 2018 Lindsay Berry, Mike West

Novel univariate models synthesise dynamic generalized linear models for binary and conditionally Poisson time series, with dynamic random effects for over-dispersion.

Bayesian Predictive Synthesis with Outcome-Dependent Pools

1 code implementation6 Mar 2018 Matthew C. Johnson, Mike West

This paper reviews background and examples of Bayesian predictive synthesis (BPS), and develops details in a subset of BPS mixture models.
