Package: shinyCTT Type: Package Title: Easy to use analysis tools for psychometric tests in the CTT framework Version: 0.4.1 Authors@R: c( person("R. Maximilian", "Bee", email = "richard.maximilian.bee@uni-jena.de", role = c("aut", "cre")), person("Michael", "Eid", email = "michael.eid@fu-berlin.de", role = "aut")) URL: https://github.com/abeeisnotabug/shinyCTT BugReports: https://github.com/abeeisnotabug/shinyCTT/issues Description: The package provides a Shiny App to analyze datasets in the framework of classical test theory based on the lavaan package. Most importantly, the model assumptions of the 5 CTT models are checked in decreasing order of complexity (tau-congeneric, essentially tau-equivalent, tau-equivalent and essentially tau-parallel, and tau-parallel) and the reliability estimators are adjusted accordingly. Moreover, it provides standard errors and confidence intervals for all parameters, including item reliabilities and error variances.
