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 properties of the ALTAAnalysisResults object, which represents the likelihood function value estimated from the accelerated life testing data analysis. |
AnalysisSettings | Sets the properties of the ALTAAnalysisOptions object, which represents the analysis settings for the accelerated life testing data analysis. |
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 | Gets 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 | Sets the properties of the ALTAGeneralOptions object, which represents miscellaneous analysis settings. |
NumStresses | Gets the total number of stresses in the data set. Integer. |
PlotUseStress(Index) | Gets or sets the use stress value for a particular stress for use in plots (not 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. |
