Adds a failure interval and associated stress level to the data set.

Syntax

  • AddFailureInterval( StartValue As Double , EndValue As Double , NumberInGroup As Integer , Stress() As Object ) Adds interval censored failures to the data set, using the specified start/end times, the number of failures during the interval and an array of stress values/profiles for all the stresses.
  • AddFailureInterval( StartValue As Double , EndValue As Double , NumberInGroup As Integer , Stress1 As Object ) Adds interval censored failures to the data set, using the specified start/end times, the number of failures during the interval and a single stress value/profile.
  • AddFailureInterval( StartValue As Double , EndValue As Double , NumberInGroup As Integer , Stress1 As Object , Stress2 As Object ) Adds interval censored failures to the data set, using the specified start/end times, the number of failures during the interval and two stress values/profiles.


Parameters

StartValue: The starting value of this failure interval.
EndValue: The ending value of this failure interval.
NumberInGroup: The number of units that failed during this interval.
Stress(): An array containing numeric stress values or references to added ALTAStressProfiles.
Stress1: A numeric stress value or reference to an added ALTAStressProfile.
Stress2: A numeric stress value or reference to an added ALTAStressProfile.

Usage Example

 'Declare a new ALTADataSet object. See ALTADataSet. 
 Dim ADS As New ALTADataSet("AddFailure_Example")
 
 'Define a new stress. See AddStressDefinition. 
 ADS.AddStressDefinition("Stress1")

 'Add 2 interval censored data points at stress = 100 to the data set. The failures occurred between time= 10 and time = 20. 
 ADS.AddSuspensions(10, 20, 2, 100)
