Exponentiated Weibull integrated hazard rate function

Share:

Description

Computes the integrated hazard rate function of the exponentiated Weibull distribution

Usage

1
iew(x, t = 1, alpha = 1, c = 1, lambda = 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

lambda

the value of lambda parameter, must be positive

c

the value of c 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. This function uses the R contributed package reliaR.
