The first reason for the growth in use of Bayesian statistics is the development of the computer-based Markov chain Monte Carlo (MCMC) simulation methods, which allow Bayesian analysis to be performed flexibly and for very complex models … A Markov chain or Markov process is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event. Informally, this may be thought of as, "What happens next depends only on the state of affairs now." A countably infinite sequence, in which the chain moves state at discrete time steps, gives a discrete-time Markov chain (DTMC). A continuous-time process is called a continuous-time Marko… indian athletes in commonwealth games 2022
