Disattenuation of Observed Correlation Due to Measurement Error.

Description

Estimate the true association between the predictor and criterion after accounting for the degree to which a true correlation is attenuated due to measurement error.

Usage

disattenuationCorrelation(
  observedAssociation,
  reliabilityOfPredictor,
  reliabilityOfCriterion
)

Arguments

observedAssociation	Magnitude of observed association (r value).
reliabilityOfPredictor	Reliability of predictor (from 0 to 1).
reliabilityOfCriterion	Reliability of criterion/outcome (from 0 to 1).

Details

Estimate the true association between the predictor and criterion after accounting for the degree to which a true correlation is attenuated due to random measurement error (unreliability).

Value

True association between predictor and criterion.
