Degradation Platform Options

In the Degradation platform, the Degradation Data Analysis red triangle menu contains the following options:

Degradation Path Style

(Not available for the Stability Test method.) Contains the following options for selecting the style of degradation path to fit:

Simple Linear Path

Enables you to fit linear degradation paths and nonlinear paths that can be transformed to linear paths. See Simple Linear Path.

Nonlinear Path

Enables you to fit nonlinear degradation paths. See Nonlinear Path.

Graph Options

Contains options for modifying the appearance of graphs in the report.

Connect Data Markers

Shows or hides lines that connect 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 specification 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 or prediction intervals for the fitted lines that are shown on the Overlay plot.

Curve Interval Alpha

Specifies the alpha level that is used for the confidence interval curves in the Overlay plot.

Show Legend

Shows or hides a legend for the markers used on the Overlay plot.

No Tab List

Arranges the Residual Plot, Inverse Prediction, and Prediction Graph tabs as a stacked report.

Prediction Settings

Opens a window that contains the following options to modify the settings that are used in the model predictions:

Upper Spec Limit

Specifies the upper specification limit.

Lower Spec Limit

Specifies the lower specification limit.

Censoring Time

Specifies the censoring time. See Inverse Prediction.

Baseline

Specifies the normal use conditions for the explanatory variable in nonlinear degradation paths. The baseline value appears on the Overlay plot as a black line.

Inverse Prediction

Specifies the interval type, alpha level, and one-sided or two-sided intervals for inverse prediction. To do inverse prediction, you must also specify the lower or upper specification limit. See Inverse Prediction.

Longitudinal Prediction

Specifies the Time value, interval type, and alpha level for longitudinal prediction. See Prediction Graph.

Applications

Contains the following options for further analysis of the degradation data:

Generate Pseudo Failure Data

Saves the predicted time that each unit crosses the specification limit to a new data table. The new data 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

Runs a stability analysis for determining estimated expiration dates. See Stability Analysis in the Degradation Platform.

See “Local Data Filters in JMP Reports”, “Redo Menus in JMP Reports”, “Group Platform”, and “Save Script Menus in JMP Reports” in Using JMP 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.

Redo

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.

Platform Preferences

Contains options that enable you to view the current platform preferences or update the platform preferences to match the settings in the current JMP report.

Save Script

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.

Note: Additional options for this platform are available through scripting. Open the Scripting Index under the Help menu. In the Scripting Index, you can also find examples for scripting the options that are described in this section.
