Sent to — interactive charts, statistical results, R code, and AI insights.
Analyze another fileStandard-library analysis: how long until customers churn, machines fail, or patients relapse — with censoring handled properly. Kaplan-Meier survival curves per group, median time-to-event with confidence intervals, a log-rank test of whether the groups truly differ, and Cox hazard ratios that say how much faster one group reaches the event than another. Works on any duration data: map a time column, an event flag, and a group.
