(At various times called the hazard function, conditional failure rate, instantaneous failure probability, instantaneous failure rate, local failure rate, a component of “risk” – see FAQs 14-17.) h (t) = f (t)/R (t)

Which is the survival function of f ( t )?

F (t) is the cumulative distribution function (CDF). It is the area under the f (t) curve from 0 to t.. (Sometimes called the unreliability, or the cumulative probability of failure.) R (t) is the survival function. (Also called the reliability function.)
