haddweibull: Additive Weibull hazard rate function

Description

Computes the hazard rate function of the additive Weibull distribution

Usage

haddweibull(x, a = 1, b = 1, c = 1, d = 1)

Arguments

x

scale or vector of positive values at which the hazard rate function needs to be computed

a

the value of a parameter (the first scale parameter), must be positive

b

the value of b parameter (the first shape parameter), must be positive

c

the value of c parameter (the second scale parameter), must be positive

d

the value of d parameter (the second shape parameter), must be positive

Value

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