dropR - Dropout Analysis by Condition
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)
