ALTADataSet Class

Member of: SynthesisAPI

Represents an ALTA standard folio data sheet. The methods and properties in this class allow you to define a data set and fit a distribution and life-stress relationship to the data.

Constructor

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

Method

Name	Description
AddFailure	Adds a failure time to the data set.
AddFailureInterval	Adds interval censored failures to the data set.
AddStressDefinition	Adds a stress type to the data set.
AddStressProfile	Adds a cProfile object, which represents a time-dependent stress profile, to the data set. Applies to the cumulative damage (CD) model only.
AddSuspension	Adds suspensions to the data set.
AddSuspensionInterval	Adds interval censored suspensions to the data set.
Calculate	Fits a life distribution and life-stress relationship to the current data set, and creates a cModel object that represents the fitted model.
ClearDataSet	Clears all data in the data set and removes the fitted model, if any.

Properties

Name	Description
AnalysisResults	Gets the ALTAAnalysisResults object that represents the likelihood function value estimated from the accelerated life testing data analysis.
AnalysisSettings	References the ALTAAnalysisOptions object, which represents the analysis settings of the accelerated life testing data analysis. Read-Only.
Calculated	Indicates whether the data set has been analyzed. Boolean. Read only.
DatasetName	Gets 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.
FittedModel	References 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.
GeneralSettings	References the ALTAGeneralOptions object, which represents the miscellaneous analysis settings. Read-Only.
NumStresses	Gets the total number of stresses in the data set. Integer.
PlotUseStress	Sets 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.
SuspensionCount	Gets the total number of suspensions in the data set. Integer.
UseCalculationProgress	Indicates whether to display the progress bar while analyzing the data set. Boolean. Default value = True.
