This work gives an overview of statistical analysis for some models multivariate discrete-valued (MDV) time series. We present observation-driven and based on higher-order Markov chains. Several extensions are highlighted including non-stationarity, network autoregressions, conditional non-linear autoregressive models, robust estimation, random fields spatio-temporal models.
