Computational Aspects of Psychometric Methods: With R
A practical guide to psychometric methods with R.
Welcome
Welcome to the online version of Computational Aspects of Psychometric Methods: With R. This book is published by Chapman & Hall/CRC Press in the Statistics in the Social and Behavioral Sciences Series.
This book provides a practical guide to psychometric methods with R. It covers a wide range of topics including validity, factor analysis, reliability, item analysis, regression models for item responses, item response theory, and differential item functioning.
The book emphasizes computational aspects and hands-on analysis using the R statistical environment, with particular focus on the ShinyItemAnalysis package for interactive test and item analysis.
R code
The R code for this book is available at https://github.com/patriciamar/PsychometricsBook/.
Interactive SIA platform
The book is accompanied by an interactive ShinyItemAnalysis platform. It provides tools for test and item analysis, item response theory modeling, and differential item functioning detection – all through an intuitive graphical interface as well as a programmatic R API.
