Fast Variational Bayes for Large Spatial Data

2026 · Journal of Computational and Graphical Statistics

Recent variational Bayes methods for geospatial regression, proposed as an alternative to computationally expensive Markov chain Monte Carlo (MCMC) sampling, have leveraged Nearest Neighbor Gaussian processes (NNGP) for scalability. Yet, these variational methods remain inferior …
