📉 Survival Analysis: Kaplan-Meier Estimator with Censored Data

Interactive Kaplan-Meier survival curve builder: generate a censored time-to-event dataset, watch the step-function survival estimate S(t) update with censoring ticks, and compare two groups with a log-rank chi-square statistic.

ControlsSubjects-per-group slider (10-150) sets cohort size; censoring-level slider (0-70%) sets dropout probability; Single group / Compare 2 groups toggle switches between one Kaplan-Meier curve and two curves (control vs. treatment) with a live log-rank chi-square and p-value; Reset button draws a new random sample.

⚙ Under the hood

Generate a cohort of subjects with random time-to-event and dropout censoring, then watch the Kaplan-Meier step-function survival curve S(t) build live with tick marks at censored times. Compare a control and treatment group side by side with a real log-rank chi-square statistic.
