Transition Probability
From Open Risk Manual
Definition
A Transition Probability for a stochastic (random) system is the probability the system will transition between given states in a defined period of time.
Let us assume a state space . The the probability of moving from state m to state n in one time step is
- The collection of all transition probabilities forms the Transition Matrix which satisfies various properties.
- When the system is observed for an infinitesimal time period, we talk about the Transition Rate.
