Fits a life distribution and life-stress relationship to the current data set, and creates a cModel object that represents the fitted model. Returns a message box that shows the estimated parameters of the fitted model.

To specify the life distribution, life-stress relationship and other analysis settings, use the AnalysisSettings and GeneralSettings properties of the associated 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()
  
 'Retrieve the fitted model. 
  Dim model As cModel
  Set model = ADS.FittedModel

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