Global Weibull

Access the analytical capabilities of a Weibull++ standard folio. The API functions related to plots that could be generated from either Weibull++ or ALTA standard folios can be found in WAPlots.

Useful resource classes may be found in Global Resources.

Classes

• WeibullAnalysisOptions Sets the WeibullDataSet.AnalysisSettings property.
• WeibullAnalysisResults the correlation coefficient, likelihood value and percent non-zero values that were estimated from the analysis, if applicable. These are equivalent to the "Rho," "LK Value" and "Pnz" results that can be shown in the Analysis Summary of the standard folio control panel.

Use the WeibullDataSet.AnalysisResults method to access these results.

• WeibullBestFitOptions This page contains the WeibullBestFitOptions Class properties that allow distributions and rankings within the Distribution Wizard in a Weibull++ folio. See BestFitSettings for settings.
• WeibullDataSet Provides the functionality of a Weibull++ standard folio, including entering data in a data set, specifying analysis settings and fitting a distribution to the data set.
• WeibullEvents all the event handlers that can be called by WeibullDataSet. To use events, you must inherit the class, override its methods and assign its instance to the Events property of a WeibullDataSet. WeibullEvents inheritance is not available in VB6/VBA.
• WeibullGeneralOptions This class describes various settings for WeibullDataSet's GeneralSettings.

Enumerations

• WeibullBayesianPriorDistribution Available prior distributions for beta.
• WeibullBayesianResultsOption Available Bayesian-Weibull result options. This includes median and mean.
• WeibullSolverCBMethod
• WeibullSolverDistribution Contains all available life distributions.

To set the specific version of the selected distribution (e.g., 2-parameter Weibull vs. mixed Weibull) for use with the WeibullDataSet.Calculate method, use the Parameters property of the WeibullAnalysisOptions class.

• WeibullSolverMethod Contains different methods for estimating the parameters of the selected distribution (e.g., rank regression X).
• WeibullSolverNumParameters Contains different forms of a life distribution (e.g., 2-parameter vs. 3-parameter).

The life distribution (e.g., Weibull vs. normal) is specified in the Distribution property of the WeibullAnalysisOptions class.

• WeibullSolverRankMethod Contains the available methods for calculating the unreliability estimates of the times-to-failure data.
