Represents a data set for accelerated life testing data analysis.

Constructor

Name Description
ALTADataSetCreates an instance of the ALTADataSet class.
ALTADataSet()A parameterized constructor for the ALTADataSet class (.NET only)


Method

Name Description
AddFailureAdds a failure time to the data set.
AddFailureIntervalAdds interval censored failures to the data set.
AddStressDefinitionAdds a stress type to the data set.
AddStressProfileAdds a cProfile object, which represents a time-dependent stress profile, to the data set. Applies to the cumulative damage (CD) model only.
AddSuspensionAdds suspensions to the data set.
AddSuspensionIntervalAdds interval censored suspensions to the data set.
CalculateFits a life distribution and life-stress relationship to the current data set, and creates a cModel object that represents the fitted model.
ClearDataSetClears all data in the data set and removes the fitted model, if any.


Properties

Name Description
AnalysisResultsGets the ALTAAnalysisResults object that represents the likelihood function value estimated from the accelerated life testing data analysis.
CalculatedIndicates whether the data set has been analyzed. Boolean. Read only.
DatasetNameGets or sets the name of the data set. String. If no name has been specified, the default name is "Set 1."
FailureCount Gets the total number of failures in the data set. Integer.
FittedModelReferences the cModel object that represents the fitted model of the accelerated life testing data analysis. From the cModel object, you can obtain results such as the reliability, mean time, failure rate, etc.
NumStressesGets the total number of stresses in the data set. Integer.
PlotUseStressSets the use stress value to be plotted (does not affect results of calculations). Double. The Index parameter is an integer that specifies the stress index, where 0 = first stress, 1 = second stress, etc.
StressRelation(Index)Gets or sets a value from the ALTASolverLSR enumeration, which specifies the stress transformation of a particular stress. Default value = 0 (exponential life-stress relationship). The Index parameter is an integer that specifies the stress index, where 0 = first stress, 1 = second stress, etc. This property applies to the general log-linear (GLL) or cumulative damage (CD) model only.
SuspensionCountGets the total number of suspensions in the data set. Integer.
UseCalculationProgressIndicates whether to display the progress bar while analyzing the data set. Boolean. Default value = True.
UseEventsIndicates whether to enable user-defined event procedures for the ALTADataSet object. Boolean. Default value = False.


Fields

Name Description
AnalysisSettingsReferences the ALTAAnalysisOptions object, which represents the analysis settings of the accelerated life testing data analysis. Read-Only.
GeneralSettingsReferences the ALTAGeneralOptions object, which represents the calculation settings for the cumulative damage life-stress model. Read-Only.


Events

Name Description
HideCalculationProgressOccurs when the calculation process is running. Hides the progress bar.
MessageOccurs when an error is produced. Displays an error message.
ShowCalculationProgressOccurs when the calculation process is running. Displays a progress bar.
UpdateCalculationProgressOccurs when the calculation process is running. Displays messages regarding the progress of the calculations.
