## Mar·kov pro·cess

(mar'kof),a stochastic process such that the conditional probability distribution for the state at any future instant, given the present state, is unaffected by any additional knowledge of the past history of the system.

## Markov process

EBMA technique of decision analysis that contrasts to standard decision tree analysis, in which a patient moves in one direction through states—e.g., from not treated, to treated, to final outcome—which may include death. In a Markov process, a hypothetical patient could move between states, backwards and forward between continuous ambulatory peritoneal dialysis and haemodialysis, with the caveat that some states—the so-called absorbing states—once entered, cannot be left (e.g., death).

Theoretical medicine

A stochastic process in which the conditional probability distribution for a system’s state at any given instant is unaffected by the system’s previous state.

## Markov process

Theoretical medicine A stochastic process in which the conditional probability distribution for a system's state at any given instant is unaffected by that system's previous state## Markov,

**Markov chaining**- a theory used in psychiatry.

**Markov process**- a process such that the conditional probability distribution for the state at any future instant, given the present state, is unaffected by any additional knowledge of the past history of the system.
