Disattenuate a Cohen's d estimate for unreliability in the continuous variable

Description

Measurement error (i.e. the complement of reliability) results in a downward bias of observed effect sizes. This attenuation can be reversed by disattenuation.

Usage

disattenuate.d(d, reliability)

Arguments

`d`	The (attenuated) value of Cohen's d (i.e. the value as observed in the sample, and therefore attenuated (decreased) by measurement error in the continuous variable).
`reliability`	The reliability of the measurements of the continuous variable

Value

The disattenuated value of Cohen's d
