ECctmc (version 0.2.5)

sample_path_unif2: Simulate a sample path from an endpoint conditioned CTMC by uniformization using pre-computed eigen-values (assumes that all eigenvalues are real).

Description

Simulate a sample path from an endpoint conditioned CTMC by uniformization using pre-computed eigen-values (assumes that all eigenvalues are real).

Usage

sample_path_unif2(a, b, t0, t1, Q, eigen_vals, eigen_vecs, inverse_vecs)

Arguments

a, b

States at the interval endpoints, provided as integers corresponding to rows of the CTMC rate matrix.

t0, t1

times of the interval endpoints

Q

CTMC rate matrix

eigen_vals

vector of eigen values of Q.

eigen_vecs

matrix of eigen vectors of Q.

inverse_vecs

inverse of the eigen vector matrix.

Value

matrix whose first column is the sequence of transition times bookended by interval endpoints, and whose second column is the sequence of states
