startbernexp: Rough parameter estimate for the Bernoulli-Exponential distribution

Description

Estimates rough starting values for the Bernoulli-Exponential distribution using the method of moments for the rate parameter. The probability of non-zero events is estimated as the fraction of values that are larger than zero.

Usage

startbernexp(x)

Arguments

x

numeric vector.

Value

A list containing:

prob

probability of non-zero event.

rate

rate parameter of the Exponential distribution.
