startbernlnorm: Rough parameter estimate for the Bernoulli-Log-Normal distribution

Description

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

Usage

startbernlnorm(x)

Arguments

x

numeric vector.

Value

A list containing:

prob

probability of non-zero event.

meanlog

meanlog parameter of the Log-Normal distribution.

sdlog

sdlog parameter of the Log-Normal distribution.
