A Step-by-Step Guide to Applying the Rasch Model Using R : A Manual for the Social Sciences

This new edition provides a step-by-step guide to applying the Rasch model in R, a probabilistic model used by researchers across the social sciences to measure unobservable (“latent”) variables.Although the focus is on simple R code, the book provides updated guidance through the point-and-click menus of BlueSky Statistics software. The book covers all Rasch models frequently used in social sciences, from the Simple Rasch model to the Rating Scale, Partial Credit, and Many-Facets Rasch models.Using a pragmatic approach to model-data fit, this book offers helpful practical examples to investigate Rasch model assumptions.In addition to traditional Rasch model approaches, it introduces the Rasch model as a special case of a Generalized Mixed Effects Model.Readers will also benefit from the online support material which includes all the code used in the book in downloadable and useable files. It also provides a comprehensive guide to R programming and practical guidance on using BlueSky Statistics software's point-and-click menus.This dual approach enables readers to experiment with data analysis using the provided data sets, enhancing their understanding and application of statistical concepts.It will be a valuable resource for both students and researchers who want to use Rasch models in their research.
