iloglogistic: Log-logistic integrated hazard rate function

In ActuDistns: Functions for actuarial scientists

Description

Computes the integrated hazard rate function of the log-logistic distribution

Usage

iloglogistic(x, t = 1, alpha = 1, sigma = 1)

Arguments

x	scale or vector of positive values at which the integrated hazard rate function needs to be computed
t	scale or vector of positive values at which the integrated hazard rate function needs to be computed, must be of the same length as x
alpha	the value of alpha parameter, must be positive
sigma	the value of sigma parameter, must be positive

Value

An object of the same length as x, giving the hazard rate function values computed at x and t

Note

If incorrect values or inconsistent lengths are input for x, t or the model parameters then NaNs will be returned as the output.
