getSter {DstarM}

Estimate variance of nondecision density

Description

Estimate variance of nondecision density

Usage

getSter(res)

Arguments

res

An object of class D*M.

Details

The object res can either be output from estDstarM or output from estND. if the former is supplied, getSter attempts to calculate the variance of the nondecision distribution by subtracting the variance of the model distribution from the variance of the data distribution. If the latter is supplied, the variance is calculated by integrating the nondecision distribution.
