Multiple Systems (Known Operating Times) Data Reference Example

This example compares the results for multiple systems (known operating times) data.

MIL-HDBK-189A, Section 6.3.1.6.4, pg. 156, 2009.

The following table shows the data.

The book has the following results:


 * Beta = 0.716, Lambda = 0.454


 * DMTBF = 15.5 hours


 * Using significance level = 0.05. CVM = 0.091. Critical value = 0.218. Since CVM < critical value can fail to reject hypothesis that model fits the data.
