COMPETING RISKS AND ANALYSIS OF FAILURE TIMES

Abstract

A competing risks is an event that either hinders  the observations of the event of the event of interest or modified the chance that this events occurs.

Competing risk occurs when subject can experience one or more events or outcomes which compete with outcomes of interest.

In a typical analysis of time to event data competing events may be censored  or incorporated into composite end points. The presence of competing events violates the assumptions of independent censoring which is the basis of standard survival analysis techniques.

The paper deals with principles of the competing risk analysis and approaches for analysing data with competing events.
