| Sumario: | The writers demonstrate that the maximum likelihood (ML) estimates of the parameters of the Goel-Okumoto software reliability model are not consistent because the observation period for observed software failure extends to infinity. They indicate that the properties of the ML estimators as the observation period grows longer are especially important when the observation period matches the test interval, as extension of the test interval is the most basic way for improving the reliability of software before it is released. They observe that besides supplying insight into interpreting ML estimators in actual applications, their findings also have pedagogical value as a demonstration that asymptotic properties of ML estimators cannot be presumed. |
