Density, distribution, quantile functions and other utilities for the Coxian phase-type distribution with two phases.

This is the distribution of the time to reach state 3 in a continuous-time Markov model with three states and transitions permitted from state 1 to state 2 with intensity lambda1 state 1 to state 3 intensity mu1 and state 2 to state 3 intensity mu2. States 1 and 2 are the two “phases” and state 3 is the “exit” state.


An disfribution following this distribution can be seen as coming from a mixture of two populations:. This can be useful for choosing intuitively reasonable initial values for procedures to fit these models to data.

Phase-type distribution – Wikipedia

This is the minimum hazard ratio for decreasing hazards. This is a special case of the n-phase Coxian phase-type distribution, which in turn is a special case of the phasw phase-type distribution.

The actuar R package implements a general n-phase distribution defined by the time to absorption of a general continuous-time Markov chain with a single absorbing state, where the process starts in one of the transient states with a given probability. An R Package for Actuarial Science.
