Its worked examples in R demonstrate how to apply the methods to real-world examples and how to interpret the resulting output.\u003c\/p\u003e\u003cp\u003eIn addition to motivating and presenting the Rasch model, the book covers different methods for parameter estimation and for assessing fit and differential item functioning (DIF). While focusing on the Rasch model, it also addresses a variety of other dichotomous and polytomous Rasch and item response theory (IRT) models, such as two-parameter logistic (2PL) and Partial Credit models, and extensions, including mixture Rasch models and computerized adaptive testing (CAT).\u003c\/p\u003e\u003cp\u003eTheory is presented in a self-contained way. All necessary mathematical and statistical background is contained in the chapters and appendices. The book also provides detailed, step-by-step instructions for getting started with R and using the eRm, mirt, TAM and rstan packages for fitting Rasch models.\u003c\/p\u003e","brand":"Taylor \u0026 Francis Ltd","offers":[{"title":"Default Title","offer_id":54247557431640,"sku":"9781032265582","price":210.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9781032265582.jpg?v=1777799751","url":"https:\/\/agendabookshop.com\/products\/introduction-to-the-rasch-model-with-examples-in-r-1","provider":"Agenda Bookshop","version":"1.0","type":"link"}
