Weibull hazard rate function

Description

Computes the hazard rate function of the Weibull distribution

Usage

1
hweibull(x, alpha = 1, sigma = 1)

Arguments

x

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

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

Note

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