A New Software Reliability Growth Model: Multigeneration Faults and a Power-Law Testing-Effort Function

Table 1

Detected faults (days from release and number of errors) for three versions of Apache, 2.0.35/2.0.36/2.0.39. Note that some failure data is not shown due to page limit. For example, as no faults are detected on the 42nd day in Apache 2.0.35, no failure data is shown on this day.
