New preprint and R package for causal inference and Bayesian modelling for complex panel data using Dynamic Multivariate Panel Models (DMPMs):
https://osf.io/preprints/socarxiv/mdwu5/
https://docs.ropensci.org/dynamite/index.html

DMPM supports
(1) joint modelling of multiple response variables from mixed distributions
(2) time-varying regression coefficients
(3) posterior predictive simulations for estimation of long-term causal effects
(4) Suitable for both large N and large T case as well as for univariate time series case (N=1)
