tables(Actuarial) analysis (CutlerEderer method) The
length of time intervals used in the analysis is somewhat arbitrary but should
be selected so that the number of censored observations in any interval is
small. KaplanMeier
(product limit) Survival Analysis with Greenwood 95%CI It
is similar to actuarial analysis except that time since entry in the study is
not divided into intervals. So, it is especially appropriate in studies
involving a small number of patients (<30). Hazard
