Estimates the parameters of the data set, based on the settings specified in the AnalysisSettings property of the class. Returns a message box that shows the values of the parameters.

In addition, the method automatically creates a retrievable cModel object that represents the fitted model from the life data analysis.

Syntax

.Calculate


Example

VB.NET

 'Declare a new WeibullDataSet object.  
  Dim WDS As New WeibullDataSet
  
 'Add failure times to the data set. 
  Call WDS.AddFailure(100, 1)
  Call WDS.AddFailure(120, 1)
  Call WDS.AddFailure(130, 1)  
 
 'Set the life distribution. 
  WDS.AnalysisSettings.Distribution = WeibullSolverDistribution_Weibull
  WDS.AnalysisSettings.Parameters = WeibullSolverNumParameters_MS_2Parameter
 
 'Fit the data to the life distribution, using all default analysis settings. 
  WDS.Calculate()
  
 'Retrieve the fitted life distribution model. 
  Dim model As cModel
  Set model = WDS.FittedModel

 'Using the model, calculate the reliability at 100 hrs and display the result. 
  Dim r As Double
  r = model.reliability(100)
  MsgBox(r)

VB.NET

 'Declare a new WeibullDataSet object.  
  Dim WDS As New WeibullDataSet
  
 'Add failure times to the data set. 
  WDS.AddFailure(100, 1)
  WDS.AddFailure(120, 1)
  WDS.AddFailure(130, 1)  
 
 'Set the life distribution. 
  WDS.AnalysisSettings.Distribution = WeibullSolverDistribution.Weibull
  WDS.AnalysisSettings.Parameters = WeibullSolverNumParameters.MS_2Parameter
 
 'Fit the data to the life distribution, using all default analysis settings. 
  WDS.Calculate()
  
 'Retrieve the fitted life distribution model. 
  Dim model As cModel
  model = WDS.FittedModel

 'Using the model, calculate the reliability at 100 hrs and display the result. 
  Dim r As Double
  r = model.reliability(100)
  MsgBox(r)
