Title: Dropout Analysis by Condition
Description: Analysis and visualization of dropout between conditions
        in surveys and (online) experiments. Features include
        computation of dropout statistics, comparing dropout between
        conditions (e.g. Chi squared), analyzing survival (e.g.
        Kaplan-Meier estimation), comparing conditions with the most
        different rates of dropout (Kolmogorov-Smirnov) and visualizing
        the result of each in designated plotting functions. Article
        published in _Behavior Research Methods_ on 'dropR' by the
        authors: Dropout analysis: A method for data from
        Internet-based research and 'dropR', an R-based web app and
        package to analyze and visualize dropout. (2025)
