• Goel-Okumoto Software Reliability Model - Abstract: . An automated version of the Goel-Okumoto Nonhomogeneous Poisson Process Software Reliability Model which runs on an IBM-PC or compatible under MS-DOS 2.11 or higher. Features include the ability to find maximum likelihood estimators of the parameters defining the model by using either the Newton-Raphson or Muller's method; a goodness-of-fit test based on a Kolmogorov-Smirnovstatistic; estimation of remaining faults, cumulative failures, and reliability; and estimation of the optimal release time based on certain cost criteria
