do_ks

This test is used for survival analysis between the most extreme conditions,
so the ones with the most different rates of dropout.
This function automatically prepares your data and runs <code><a href="/link/stats%3A%3Aks.test()?package=dropR&version=1.0.3" data-mini-rdoc="dropR::stats::ks.test()">stats::ks.test()</a></code> on it.

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 square), 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.
