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


Remarks: To specify the distribution, life-stress relationship 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 ALTADataSet object.

Syntax

.Calculate()


Example

VBA

 'Declare a new ALTADataSet object. 
  Dim ADS As New ALTADataSet
 
 'Define a stress type with use stress level = 300. 
  Call ADS.AddStressDefinition("Stress1",,300)

 'Add failure times for Stress1 = 190 and 235. 
  Call ADS.AddFailure_2(100, 1, 190)
  Call ADS.AddFailure_2(120, 1, 190)
  Call ADS.AddFailure_2(130, 1, 235)
  Call ADS.AddFailure_2(140, 1, 235)

 'Analyze the data set, using all default analysis settings. 
  Call ADS.Calculate()
   
 'Calculate the reliability at 100 hrs and display the result. 
  Dim r As Double
  r = ADS.FittedModel.Reliability(100)
  MsgBox("Reliability at 100 hrs: " & r)
VB.NET

  ADS.AddFailure(130, 1, 235)

  ADS.Calculate()

  Dim r As Double
