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

In qmap: Statistical Transformations for Post-Processing Climate Model Output

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.

Note

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