In probability theory and statistics, the term Markov property refers to the memoryless property of a stochastic process. It is named after the Russian mathematician Andrey Markov. The term strong Markov property is similar to the Markov property, except that the meaning of "present" is defined in terms of a random variable known as a stopping time. SpletMarkov models have been heavily used for their predictive power. Markov models assume that the probability of an occurring event is dependent only on the current state of a system. As a simple example, imagine that we would like to track the probability of a Sunny (S) day or Rainy (R) day of weather.

SpletA common assumption in multi-state models is to constraint transitions to be dependent upon a subject’s current state, and not on their disease history. This is known as the Markov assumption, and under it model tting and predicting is straightforward. The assumption is rarely evaluated or relaxed, since accessible methods are limited.
