Statistical Tests

When you use the Crow-AMSAA (NHPP) or Crow Extended models, RGA automatically performs statistical tests on the calculated data set. The results of the tests help you to evaluate how well the model fits the data. Only the test that applies to the data type and model you are using will appear in the results. The results are displayed on the standard folio control panel, and can also be displayed in a report by choosing Growth Data > Analysis > Statistical Tests.

The following tests evaluate the hypothesis that the failure times follow a non-homogeneous Poisson process (NHPP). The ReliaWiki resource portal provides more information about these tests at http://www.reliawiki.org/index.php/Crow-AMSAA_(NHPP).

The following tests apply to multiple systems analysis only. The ReliaWiki resource portal has more information about these tests at http://ReliaWiki.org/index.php/Hypothesis_Tests.

Tip: You can set the default significance level for the statistical tests by entering a value in the RGA Standard Folios page of the Application Setup, or by changing the value on-the-fly from the Analysis page of the standard folio control panel.

The following tools are also available in RGA, but are not automatically performed when you calculate the data set:
