An Empirical Assessment and Validation of Redundancy Metrics Using Defect Density as Reliability Indicator
Table 2
Sum up of redundancy metrics.
| Metric | Purpose | Equation | Metric hypothesis |
| ISR | Measures the redundancy (excess bits) of the program’ initial state | | The proposed redundancy metrics can be exploited to monitor software reliability | FSR | Measures the redundancy (excess bits) of the program’ final state | | FR | Measures redundancy of the program functionality | | NI | Mapping between initial states to the same final ones | |
