Review of Last lecture (2) Implication of these functions: I The survival function S(x) is the probability of an individual surviving to time x. I The hazard function h(x), sometimes termed risk function, is the chance an individual of time x experiences the event in the next instant in time when he has not experienced the Week 2: Non-Parametric Estimation in Survival Models.

Examples: Event Cancer surgery, radiotherapy, chemotherapy → … No further reading required, lecture notes (and the example sheets) are sufficient. The important di⁄erence between survival analysis and other statistical analyses which you have so far encountered is the presence of censoring. Estimation for Sb(t). In survival analysis we use the term ‘failure’ to de ne the occurrence of the event of interest (even though the event may actually be a ‘success’ such as recovery from therapy). Outline Basic concepts & distributions – Survival, hazard – Parametric models – Non-parametric models Simple models 8. 8. Prepared by Dr. Herenia P. Lawrence DEN 1015H LECTURE NOTES Session 12 Survival Analysis Survival Analysis is concerned with studying the time between entry to a study and a subsequent event (time-to-event analysis).

In survival analysis the outcome istime-to-eventand large values are not observed when the patient was lost-to-follow-up before the event occurred. Com-pared to the notes from three years ago, several details and very few subjects have been changed. I Instead of looking at the cdf, which gives the probability of surviving at most t time units, one prefers to look at survival beyond a given point in time.
