WeibullDataSet Class

Instantiate this class to be able to fit a Weibull model from your raw data.

Constructors

This section contains information on how to create a new Weibull++ folio.

• New WeibullDataSet Creates a new class that can be used to fit a model from Weibull raw data.
  

Methods

This section contains the methods that a user might use to manipulate their Weibull++ data set. A user may use these methods to add failures, suspensions, failure intervals, suspension intervals, free forms, calculate the data set, or clear the data set. This section should be configured after the data set has been created.

• AddFailure Adds failure times to the data set, using the specified time and number of failures at that time.
• AddSuspension Adds suspensions to the data set, using the specified time and number of suspensions at that time.
• AddFailureInterval Adds interval censored failures to the data set, using the specified start/end times and number of failures that occurred within the interval.
• AddSuspensionInterval Adds interval censored suspensions to the data set, using the specified start/end times and number of suspensions for that interval.
• AddFreeForm Adds a free-form data point to the data set, using the specified time and percentage values.
• Calculate Fits the distribution to the current data set using the settings specified in the AnalysisSettings property.
• CalculateBestFit Automatically finds the best fitting distribution and fits that distribution to the current data set using the settings specified in the BestFitSettings property.
• ClearDataSet Clears all data in the data set and removes the fitted model, if any.

Properties

This section contains properties that a user may use to analyse the data set. The user may choose to have a data set name, have a count of failures, and more.

• AnalysisResults Gets the correlation coefficient, likelihood value and percent non-zero values that were estimated from the analysis, if applicable.
• DatasetName Gets or sets the name of the data set, which will be displayed on any plot you create.
• GeneralSettings Sets some of the Application Setup calculation options that can apply to both the Calculate and CalculateBestFit methods.
• AnalysisSettings Sets the control panel settings for use with the Calculate method.
• BestFitSettings Sets the Distribution Wizard and control panel settings for use with the CalculateBestFit method.
• FittedModel Gets the fitted model from the life data analysis. This property is cleared if the analysis could not be completed.
• FailureCount Gets the total number of failures in the data set.
• SuspensionCount Gets the total number of suspensions in the data set.
  

Events

This section allows the user to create and display messages, questions, calculation progress, and more.

• Events 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.
