dpch: Survival Distributions with piece-wise Constant Hazards

Description

Densitiy, distribution function, quantiles, random numbers, hazard function, cumulative hazard function and survival function of survival distributions with piece-wise constant hazards (picewise exponential distributions).

Usage

dpch(x, t, lambda)
ppch(q, t, lambda)
qpch(p, t, lambda)
rpch(n, t, lambda, discrete = FALSE)
hpch(x, t, lambda)
chpch(x, t, lambda)
spch(q, t, lambda)

Value

dpch gives the density evaluated at x.

ppch gives the distribution function evaluated at q.

qpch gives the p-quantiles.

rpch gives n random numbers.

hpch gives the hazard function evaluated at x.

chpch gives the cumulative hazard function evaluated at x.

spch gives the survival function evaluated at q.
