hesela.devSurvival function
The survival function S(t) = P(T > t) is the probability that a time T to a defined event exceeds t, measured from a specified time origin.
Specify the drive population, failure event, time origin and units. S(t) is dimensionless and equals 1 - F(t); it is not an annualized event rate. [1] For a drive surviving to age a, survival for another u units of time is S(a + u) / S(a), for u >= 0 and S(a) > 0, using the same population and time origin. This follows from conditional probability, not a constant-hazard assumption.
