startbernweibull: Rough parameter estimate for the Bernoulli-Weibull distribution

Description

Estimates rough starting values for the Bernoulli-Weibull distribution using the method of moments for the shape and the scale parameters. The probability of non-zero events is estimated as the fraction of values that are larger than zero.

Usage

startbernweibull(x)

Arguments

x

numeric vector.

Value

A list containing:

prob

probability of non-zero event.

scale

scale parameter of the weibull distribution.

shape

shape parameter of the weibull distribution.
