Maximilian Bee)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.https://github.com/r-universe/abeeisnotabug/actions/runs/37926140635Wed, 30 Sep 2026 08:22:42 GMTshinyCTT0.4.1successhttps://abeeisnotabug.r-universe.devhttps://github.com/abeeisnotabug/shinyCTT
