.
ContinuousMarkovProcess[p0, q]
represents a Markov process with initial state probability vector
.
ContinuousMarkovProcess[..., m,

.
ContinuousMarkovProcess[..., g]
represents a Markov process transition rate matrix from the graph g.
DetailsDetails
- ContinuousMarkovProcess is also known as a continuous-time Markov chain.
- ContinuousMarkovProcess is a continuous-time and discrete-state random process.
- The states of ContinuousMarkovProcess are integers between 1 and
, where
is the length of transition rate matrix q. - For infinitesimal time dt,
gives the probability that the process transitions from state i to state j over the next dt units of time q
i, j
dt=Probability[x[t+dt]=j
x[t]=i]. - The time the process stays in state i before transitioning follows ExponentialDistribution[-qii].
- The transition matrix m specifies conditional transition probabilities m
i, j
=Probability[x[tk+1]=j
x[tk]=i], where
is the state at time
, and the transition rate
specifies that the time between events in state
follows ExponentialDistribution[
i]. - The transition matrix in the case of a graph g is constructed to give equal probability of transitioning to each incident vertex with unit transition rates.
- ContinuousMarkovProcess allows q to be an
×
matrix where
and
for
with rows that sum to 0,
can be an integer between 1 and
,
is a vector of length
of non-negative elements that sum to 1, m is an
×
matrix with non-negative elements and rows that sum to 1, and
is a vector of length
with positive elements. - ContinuousMarkovProcess can be used with such functions as MarkovProcessProperties, PDF, Probability, and RandomFunction.
