Rough parameter estimate for the Bernoulli-Weibull distribution

Share:

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

1

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.

Note

In this package startbernweibull is intended to be used in conjunction with fitQmapDIST (and mledist) with parameter distr="bernweibull".
