# WeibullDataSet Class

Member of: SynthesisAPI

Represents a data set for life data analysis.

## Constructor

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

## Methods

Name Description
Calculate Fits a life distribution to the current data set and creates a cModel object that represents the fitted model.
CalculateBestFit Determines 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.
ClearDataSet Clears all data in the data set and removes the fitted model, if any.

## Properties

Name Description
AnalysisResults Gets the WeibullAnalysisResults object that represents the correlation coefficient, likelihood ratio and PNZ values from the life data analysis.
Calculated Indicates whether the data set has been analyzed. Boolean. Read only.
DataSetName Gets or sets the name of the data set. String. If no name has been specified, the default name is "Set 1."
FailureCount Gets the total number of failures in the data set. Double
FittedModel References 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.
SuspensionCount Gets the total number of suspensions in the data set. Double
UseCalculationProgress Indicates whether to display the progress bar while analyzing the data set. Boolean. Default value = True.
UseEvents Indicates whether to enable user-defined event procedures for the WeibullDataSet object. Boolean. Default value = False.

## Fields

Name Description
AnalysisSettings References the WeibullAnalysisOptions object, which represents the analysis settings for the Calculate method. Read-Only.
BestFitSettings References the WeibullBestFitOptions object, which represents the analysis settings for the CalculateBestFit method. Read-Only.
GeneralSettings References the WeibullGeneralOptions object, which represents the calculation settings for both the Calculate and CalculateBestFit methods. Read-Only.

## Events

Name Description
GetDistrParameters Occurs when there is insufficient data to fit a model. Displays a prompt for entering the parameters of the distribution.
HideCalculationProgress Occurs when the calculation process is running. Hides the progress bar.
Message Occurs when an error is produced. Displays an error message.
Question Occurs when an answer to a question is required. Displays a message box with yes and no options.
ShowCalculationProgress Occurs when the calculation process is running. Displays a progress bar.
UpdateCalculationProgress Occurs when the calculation process is running. Displays messages regarding the progress of the calculations.
