Attenuation of True Correlation Due to Measurement Error.

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).

Value

Observed correlation between predictor and criterion.

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).
