hazuh: Distributional Functions given a U-shaped Hazard Function

Description

Given an object of class uh: hazuh computes the hazard values; chazuh computes the cumulative hazard values; survuh computes the survival function values; denuh computes the density function values.

Usage

hazuh(t, h)
chazuh(t, h)
survuh(t, h)
denuh(t, h)

Arguments

t

time points at which the function is to be evaluated.

h

an object of class uh.

Value

• A numeric vector of the function values.
