Research overview

Submissions:

Papageorgiou, G. (2020+). Bayesian semiparametric modelling of covariance matrices for multivariate longitudinal data. arXiv

Software:

R package BNSP: Provides Markov chain Monte Carlo algorithms for non- and semi-parametric Bayesian models. Available methods include: 1. variable selection, 2. generalized additive models and automatic function regularization, 3. joint mean-covariance models for univariate, multivariate and longitudinal multivariate responses.

R package mixcat: Fits mixed effects multinomial (ordinal and nominal) regression models with nonparametric mixing
