Member of: SynthesisAPI


Represents a data set for life data analysis.

Constructor

Name Description
WeibullDataSetCreates an instance of the WeibullDataSet class.
WeibullDataSet()A parameterized constructor for the WeibullDataSet class. (.NET only)


Methods

Name Description
AddFailureAdds a failure time to the data set.
AddFailureIntervalAdds interval censored failures to the data set.
AddFreeFormAdds a free-form data point to the data set.
AddSuspensionAdds suspensions to the data set.
AddSuspensionIntervalAdds interval censored suspensions to the data set.
CalculateFits a life distribution to the current data set and creates a cModel object that represents the fitted model.
CalculateBestFitDetermines which of the selected life distributions best fits the data set (similar to the Distribution Wizard feature in Weibull++) and creates a cModel object that represents the fitted model of the recommended distribution.
ClearDataSetClears all data in the data set and removes the fitted model, if any.


Properties

Name Description
AnalysisResultsGets the WeibullAnalysisResults object that represents the correlation coefficient, likelihood ratio and PNZ values from the life data analysis.
CalculatedIndicates whether the data set has been analyzed. Boolean. Read only.
DataSetNameGets or sets the name of the data set. String. If no name has been specified, the default name is "Set 1."
FailureCountGets the total number of failures in the data set. Double
FittedModelReferences the cModel object that represents the fitted model of the life data analysis. From the cModel object, you can obtain results such as the reliability, mean time, failure rate, etc.
SuspensionCountGets the total number of suspensions in the data set. Double
UseCalculationProgressIndicates whether to display the progress bar while analyzing the data set. Boolean. Default value = True.
UseEventsIndicates whether to enable user-defined event procedures for the WeibullDataSet object. Boolean. Default value = False.

Fields

Name Description
AnalysisSettingsReferences the WeibullAnalysisOptions object, which represents the analysis settings for the Calculate method. Read-Only.
BestFitSettingsReferences the WeibullBestFitOptions object, which represents the analysis settings for the CalculateBestFit method. Read-Only.
GeneralSettingsReferences the WeibullGeneralOptions object, which represents the calculation settings for both the Calculate and CalculateBestFit methods. Read-Only.


Events

Name Description
GetDistrParametersOccurs when there is insufficient data to fit a model. Displays a prompt for entering the parameters of the distribution.
HideCalculationProgressOccurs when the calculation process is running. Hides the progress bar.
MessageOccurs when an error is produced. Displays an error message.
QuestionOccurs when an answer to a question is required. Displays a message box with yes and no options.
ShowCalculationProgressOccurs when the calculation process is running. Displays a progress bar.
UpdateCalculationProgressOccurs when the calculation process is running. Displays messages regarding the progress of the calculations.
