In petersenlab: A Collection of R Functions by the Petersen Lab

Attenuation of True Correlation Due to Measurement Error.

Description

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

Usage

attenuationCorrelation(
  trueAssociation,
  reliabilityOfPredictor,
  reliabilityOfCriterion
)

Arguments

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

Details

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

Value

Observed correlation between predictor and criterion.

Examples

attenuationCorrelation(
  trueAssociation = .7,
  reliabilityOfPredictor = .9,
  reliabilityOfCriterion = .85)
