This example compares the results for grouped data.
Reference Case
MIL-HDBK -189A, Section 6.3.1.7.5, pg. 162, 2009.
Data
| Termination Time = 100 hours | |
|---|---|
| Failures in Interval | Interval End Time |
| 13 | 20 |
| 16 | 40 |
| 5 | 60 |
| 8 | 80 |
| 7 | 100 |
Result
Beta = 0.753, Lambda = 1.53
DMTBF = 2.6 hours
[math]\displaystyle{ \,\!X^{2} }[/math] = 5.5, critical value = 7.8 (Assume significance level = 0.1. Since [math]\displaystyle{ \,\!X^{2} }[/math] < critical value can fail to reject hypothesis that the Crow-AMSAA model fits the data).
