Description

Psychometric Evaluation Using Relative Excess Correlations.

Modern results of psychometric theory are implemented to provide users with a way of evaluating the internal structure of a set of items guided by theory. These methods are discussed in detail in VanderWeele and Padgett (2024) <doi:10.31234/osf.io/rnbk5>. The relative excess correlation matrices will, generally, have numerous negative entries even if all of the raw correlations between each pair of indicators are positive. The positive deviations of the relative excess correlation matrix entries help identify clusters of indicators that are more strongly related to one another, providing insights somewhat analogous to factor analysis, but without the need for rotations or decisions concerning the number of factors. A goal similar to exploratory/confirmatory factor analysis, but 'recmetrics' uses novel methods that do not rely on assumptions of latent variables or latent variable structures.

recmetrics

The goal of recmetrics is to provide users with the ability to conduct psychometric evaluation without relying on assumptions of the latent variable structure following the work of VanderWeele and Padgett (2024).

Installation

install.packages("recmetrics")

You can install the development version of recmetrics from GitHub with:

# install.packages("devtools")
devtools::install_github("noah-padgett/recmetrics")

Example

This is a basic example which shows you how to provide an evaluation of the interval structure of a set of items on a survey similar to confirmatory factor analysis. Using the a prior groups of items on each domain, we can construct a pattern matrix of the relative excess correlations.
