Example

The following example demonstrates how to initialize the goodness of fit analysis settings for a particular WeibullDataSet object. 

VBA

 'Declare a new WeibullDataSet object. 
  Dim WDS As New WeibullDataSet
 
 'Specify the analysis settings. 
  WDS.BestFitSettings.AllowAllDistributions
  WDS.BestFitSettings.Analysis = WeibullSolverMethod_MLE
  WDS.BestFitSettings.ConfBounds = WeibullSolverCBMethod_FisherMatrix
  WDS.BestFitSettings.RankingMethod = WeibullSolverRankMethod_Median
  WDS.BestFitSettings.SortBeforeCalculations = True
  WDS.BestFitSettings.UngroupGroupedData = False
  WDS.BestFitSettings.UseRSRegression = False
  WDS.BestFitSettings.UseSpecialSort = True

 'Add failure times to the data set. 
  Call WDS.AddFailure(10, 1)
  Call WDS.AddFailure(20, 1)
  Call WDS.AddFailure(30, 1)  

 'Analyze the data set. 
  Call WDS.CalculateBestFit()

VB.NET

 'Declare a new WeibullDataSet object. 
  Dim WDS As New WeibullDataSet
 
 'Specify the analysis settings. 
  Call WDS.BestFitSettings.AllowAllDistributions
  WDS.BestFitSettings.Analysis = WeibullSolverMethod.MLE
  WDS.BestFitSettings.ConfBounds = WeibullSolverCBMethod.FisherMatrix
  WDS.BestFitSettings.RankingMethod = WeibullSolverRankMethod.Median
  WDS.BestFitSettings.SortBeforeCalculations = True
  WDS.BestFitSettings.UngroupGroupedData = False
  WDS.BestFitSettings.UseRSRegression = False
  WDS.BestFitSettings.UseSpecialSort = True

 'Add failure times to the data set. 
  WDS.AddFailure(10, 1)
  WDS.AddFailure(20, 1)
  WDS.AddFailure(30, 1)  

 'Analyze the data set. 
  WDS.CalculateBestFit()
