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

reliabilityOfCriterion |
Reliability of criterion/outcome (from 0 to 1). |
Details
