attenuationCorrelation

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.

A collection of R functions that are widely used by the Petersen
Lab. Included are functions for various purposes, including evaluating the
accuracy of judgments and predictions, performing scoring of assessments,
generating correlation matrices, conversion of data between various types,
data management, psychometric evaluation, extensions related to latent
variable modeling, various plotting capabilities, and other miscellaneous
useful functions. By making the package available, we hope to make our
methods reproducible and replicable by others and to help others perform
their data processing and analysis methods more easily and efficiently. The
codebase is provided in Petersen (2024) <doi:10.5281/zenodo.7602890> and on
CRAN: <doi: 10.32614/CRAN.package.petersenlab>. The package is described in
"Principles of Psychological Assessment: With Applied Examples in R"
(Petersen, 2024, 2025) <doi:10.1201/9781003357421>,
<doi:10.25820/work.007199>, <doi:10.5281/zenodo.6466589>.
