abeeisnotabug/shinyCTT: Easy to use analysis tools for psychometric tests in the CTT framework

Provides a Shiny App to analyze datasets in the framework of classical test theory by providing wrapper functions for the lavaan package. Most importantly, the main function rigorously checks the model assumptions of the 5 CTT models in decreasing order of complexity (tau-kongeneric, essentially tau-equivalent, tau-equivalent and essentially tau-parallel, and tau-parallel) and adjusts its reliability estimators accordingly. Moreover, it provides standard errors and confidence intervals for all parameters, including item reliabilities and error variances.
