qaddweibull: Additive Weibull integrated hazard rate function

In ActuDistns: Functions for actuarial scientists

Description

Computes the integrated hazard rate function of the additive Weibull distribution

Usage

qaddweibull(x, u = 0.5, a = 1, b = 1, c = 1, d = 1)

Arguments

x	scale or vector of positive values at which the integrated hazard rate function needs to be computed
u	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
a	the value of a parameter, must be positive
b	the value of b parameter, must be positive
c	the value of c parameter, must be positive
d	the value of d parameter, must be positive

Value

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

Note

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