ShinyItemAnalysis-package: ShinyItemAnalysis: Test and Item Analysis via shiny

Description Details Functions Datasets Author(s) References See Also


The ShinyItemAnalysis package contains an interactive shiny application for the psychometric analysis of educational tests, psychological assessments, health-related and other types of multi-item measurements, or ratings from multiple raters, which can be accessed using function startShinyItemAnalysis(). The shiny application covers a broad range of psychometric methods and offers data examples, model equations, parameter estimates, interpretation of results, together with a selected R code, and is therefore suitable for teaching psychometric concepts with R. It also allows the users to upload and analyze their own data and to automatically generate analysis reports in PDF or HTML.

Besides, the package provides its own functions for test and item analysis within classical test theory framework (e.g., functions gDiscrim(), ItemAnalysis(), DistractorAnalysis(), or DDplot()), using various regression models (e.g., plotCumulative(), plotAdjacent(), plotMultinomial(), or plotDIFLogistic()), and under IRT framework (e.g., ggWrightMap(), or plotDIFirt()).

Package also contains several demonstration datasets including the HCI dataset from the reference paper by Martinkova and Drabinova (2018).
