Abstract : Given a test history consisting of record of times of software failures, together with a record of both the time at which each failure occurred and the type of that failure: 1) How many faults of each type remain in the software 2) How much added time on test is required to uncover a pre-specified number of faults? 3) If testing continues for a given increment of time, how many faults of each type will be uncovered? Stochastic models of software failures composed of a super population process that generates elements of a finite population of elements that are then successively sampled is used to construct both Bayesian and non Bayesian methods of parameter and predictive inference. Predictive validation of these models is done using NASA/GODDARD Software Engineering Lab data.
