Grouped Data Reference Example

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 h 2 = 5.5, critical value = 7.8 (Assume significance level = 0.1. Since 2 < critical value can fail to reject hypothesis that the Crow-AMSAA model fits the data).
