WebFeb 6, 2012 · Considering your trick, reversing the sequence of quantiles (I'll call it q.seq here): If I understand it correctly, predict expects death quantiles, not survival. Therefore, I think it is better to supply 1 - q.seq instead of rev(q.seq).In your case it doesn't matter, because your q.seq is symmetrical, going from 0.01 death probability (= 0.99 survival) to …

Webgoes down to zero. This condition implies that the cumulative hazard must diverge, i.e. we must have ( 1) = 1. Intuitively, the event will occur with certainty only if the cumulative risk over a long period is su ciently high. There are, however, many events of possible interest that are not bound to occur. WebSurvival analysis is a branch of statistics for analyzing the expected duration of time until one event occurs, such as death in biological organisms and failure in mechanical systems. This topic is called reliability theory or reliability analysis in engineering, duration analysis or duration modelling in economics, and event history analysis in sociology.
