daddweibull: Additive Weibull pdf

In ActuDistns: Functions for actuarial scientists

Description

Computes the pdf of the additive Weibull distribution

Usage

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

Arguments

x	scale or vector of positive values at which the pdf 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 pdf values computed at x

Note

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