DEFINITION Let ''X'' be a continuous random variable with Cumulative Distribution Function ''F''(''t'') on the interval : PROPERTIES Every survival function ''R''(''t'') is Monotone Decreasing , i.e. for The Time , ''t'' = 0, represents some origin, typically the beginning of a study or the start of operation of some system. ''R''(0) is commonly unity but can be less to represent the Probability that the system fails immediately upon operation. Again, lim''t''→∞''R''(''t'') is commonly zero but can be greater to represent a system in which Eternal Life is possible. SEE ALSO |
