SEIR_prob: Transition probabilities of an SEIR process

In MultiBD: Multivariate Birth-Death Processes

Transition probabilities of an SEIR process

Description

Computes the transition pobabilities of an SIR process using the bivariate birth process representation

Usage

SEIR_prob(
  t,
  alpha,
  beta,
  kappa,
  S0,
  E0,
  I0,
  nSE,
  nEI,
  nIR,
  direction = c("Forward", "Backward"),
  nblocks = 20,
  tol = 1e-12,
  computeMode = 0,
  nThreads = 4
)

Arguments

t	time
alpha	removal rate
beta	infection rate
kappa	rate at which an exposed person becomes infective
S0	initial susceptible population
E0	initial exposed population
I0	initial infectious population
nSE	number of infection events
nEI	number of events at which an exposed person becomes infective
nIR	number of removal events
direction	direction of the transition probabilities (either Forward or Backward)
nblocks	number of blocks
tol	tolerance
computeMode	computation mode
nThreads	number of threads

Value

a matrix of the transition probabilities
