{"product_id":"using-r-for-item-response-theory-model-applications","title":"Using R for Item Response Theory Model Applications","description":"Item response theory (IRT) is widely used in education and psychology and is expanding its applications to other social science areas, medical research, and business as well. Using R for Item Response Theory Model Applications is a practical guide for students, instructors, practitioners, and applied researchers who want to learn how to properly use R IRT packages to perform IRT model calibrations with their own data.This book provides practical line-by-line descriptions of how to use R IRT packages for various IRT models. The scope and coverage of the modeling in the book covers almost all models used in practice and in popular research, including: \u003cul\u003e   dichotomous response modeling  polytomous response modeling  mixed format data modeling  concurrent multiple group modeling  fixed item parameter calibration  modelling with latent regression to include person-level covariate(s)  simple structure, or between-item, multidimensional modeling  cross-loading, or within-item, multidimensional modeling  high-dimensional modeling  bifactor modeling  testlet modeling  two-tier modelingFor beginners, this book provides a straightforward guide to learn how to use R for IRT applications. For more intermediate learners of IRT or users of R, this book will serve as a great time-saving tool for learning how to create the proper syntax, fit the various models, evaluate the models, and interpret the output using popular R IRT packages.\u003c\/ul\u003e","brand":"Taylor \u0026 Francis","offers":[{"title":"Default Title","offer_id":44556025790702,"sku":"9781138542785","price":227.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/9612\/7726\/files\/9781138542785.jpg?v=1703537495","url":"https:\/\/bookland.com.au\/products\/using-r-for-item-response-theory-model-applications","provider":"Book Land AU","version":"1.0","type":"link"}
