Red Door Analytics

Analysing the time until something happens, when for some people it has not happened yet. Those people are censored rather than missing — they carry information right up to the moment they leave, and the methods here are the ones that use it.

Also called time-to-event analysis, event history analysis.

Survival analysis: Two arms, estimated the way the data allow: the curve only steps where an event happens, the marks are people still being followed when the study stopped, and the band is what the sample size will actually support.
