Discrete-time, discrete-state multistate Markov models from the perspective of algebraic statistics

Dario Gasbarra, Kaie Kubjas, Sangita Kulathinal +3

We study discrete-time, discrete-state multistate Markov models from the perspective of algebraic statistics. These models are widely studied in event history analysis, and are cha…
