ALTA Test Plan Control Panel

For life-stress data only.

The Main page of the Test Plan's control panel gives you options to further evaluate the recommended test plan by solving for any one of the criteria in the Solve for drop-down list.

.

To solve for one of these three criteria, you must provide values for the other two. By using the Main page of control panel, you can determine whether your goals with respect to these criteria are realistic (given factors such as sample size constraints), and you can explore various possible trade-offs between the three criteria.

Tip: Weibull++ also includes a simulation tool called SimuMatic that you can use to visualize the confidence bounds associated with the bounds ratio presented in the test plans utility. The Test Plan utility uses an analytical solution that is based on the assumption of a large sample size; SimuMatic does not make any assumptions about the sample size and thus may be preferred in the case of small sample sizes.

To solve for one of these criteria, follow the steps outlined below:

The control panel also includes a Comments page that allows you to enter notes or other text that will be saved with the folio.
