Fits a life distribution to the current data set and creates a cModel object that represents the fitted model.


Remarks: To specify the distribution, parameter estimation method and other analysis settings, use the AnalysisSettings and GeneralSettings properties of the object. To return the cModel object that is produced, use the FittedModel property of the WeibullDataSet object.

Syntax

.Calculate


Example

VBA

 '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. Leave all other settings at default. 
  WDS.AnalysisSettings.Distribution = WeibullSolverDistribution_Weibull
  WDS.AnalysisSettings.Parameters = WeibullSolverNumParameters_MS_2Parameter
 
 'Analyze the data set. 
  WDS.Calculate()

 'Calculate the reliability at 100 hrs and display the result. 
  Dim r As Double
  r = WDS.FittedModel.Reliability(100)
  MsgBox("Reliability at 100 hrs: " & 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. Leave all other settings at default. 
  WDS.AnalysisSettings.Distribution = WeibullSolverDistribution.Weibull
  WDS.AnalysisSettings.Parameters = WeibullSolverNumParameters.MS_2Parameter
 
 'Analyze the data set. 
  WDS.Calculate()
  
 'Calculate the reliability at 100 hrs and display the result. 
  Dim r As Double
  r = WDS.FittedModel.Reliability(100)
  MsgBox("Reliability at 100 hrs: " & r)
