Degradation Platform Options

The Degradation red triangle menu provides the option that are described in Degradation Platform Options.

Degradation Platform Options
Option	Description
Path Definition	The Y variable at a given time is assumed to have a distribution. You can model the mean, location parameter, or median of that distribution. Mean Path is used to model the mean. Location Parameter Path is used to model the location parameter. Median Path is used to model the median of the distribution. When the Location Parameter or Median Path option is selected, a menu appears in the Model Specification. Select the distribution of the response from that menu. See Distribution Specification. Distribution Specification
Degradation Path Style	Provides options for selecting the style of degradation path to fit. Simple Linear Path is used to fit linear degradation paths, and nonlinear paths that can be transformed to linear. For more information, refer to Simple Linear Path. Nonlinear Path is used to fit nonlinear degradation paths. For more information, refer to Nonlinear Path.
Graph Options	Provides options for modifying the platform graphs. Connect Data Markers shows or hides lines connecting the points on the Overlay plot. Show Fitted Lines shows or hides the fitted lines on the Overlay plot. Show Spec Limits shows or hides the spec limits on the Overlay plot. Show Residual Plot shows or hides the residual plot. Show Inverse Prediction Plot shows or hides the inverse prediction plot Show Curve Interval shows or hides the confidence intervals on the fitted lines on the Overlay plot. Curve Interval Alpha enables you to change the alpha used for the confidence interval curves. Show Median Curves shows or hides median lines on the plot when the Path Definition is set to Location Parameter Path. Show Legend shows or hides a legend for the markers used on the Overlay plot. No Tab List shows or hides the Residual Plot, Inverse Prediction, and Prediction Graph in tabs or in stacked reports.
Prediction Settings	Provides options for modifying the settings used in the model predictions. Upper Spec Limit is used to specify the upper spec limit. Lower Spec Limit is used to specify the lower spec limit. Censoring Time is used to set the censoring time. See Inverse Prediction. Baseline is used to specify the normal use conditions for an X variable in nonlinear degradation paths. A path with this value usually results in an Overlay plot. Inverse Prediction is used to specify interval type, alpha level, and one or two-sided intervals for inverse prediction. To do inverse prediction, you must also specify the lower or upper spec limit. For more information about inverse prediction, refer to Inverse Prediction. Longitudinal Prediction is used to specify the Time value, interval type, and alpha level for longitudinal prediction. For more information about longitudinal prediction, refer to Prediction Graph.
Applications	Provides options for further analysis of the degradation data. Generate Pseudo Failure Data creates a data table giving the predicted time each unit crosses the specification limit. The table contains a Life Distribution or Fit Life by X script that can be used to fit a distribution to the pseudo failure times. Test Stability performs stability analysis. For more information, refer to Stability Analysis.

See Local Data Filter, Redo Menus, and Save Script Menusin the Using JMP book for more information about the following options:

Local Data Filter

Shows or hides the local data filter that enables you to filter the data used in a specific report.

Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.

Contains options that enable you to save a script that reproduces the report to several destinations.

Save By-Group Script

Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.
