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.
