Properties

  • Name (as string) Gets or sets the name of the model.
  • ID (as string) Gets the numerical ID of the model.
  • ProjectID (as integer) Gets the numerical ID of the project the model belongs to.
  • Type (as ModelTypeEnum) Gets the model type (e.g., 2-parameter Weibull).
  • Category (as ModelCategoryEnum) Gets the model category (e.g., reliability).
  • Designation (as string) Gets a string representing the model type (for example "2P-Weibull").
  • ErrorHappened (as boolean) Whether or not the last calculation produced an error.
  • ConfLevel (as double) Gets the confidence level that is currently used for calculations.
  • NumStresses (as integer) Gets the number of stresses in the model.

Usage Example

 'Declare the WeibullDataSet. See WeibullDataSet Constructors. 
 Dim WDS as New WeibullDataSet
 
 'Add values to the raw data. See WeibullDataSet.AddFailure. 
 WDS.AddFailure(1, 1)
 WDS.AddFailure(2, 1)
 WDS.AddFailure(3, 1)
 
 'Calculate the fitted model using default settings. See WeibullDataSet.Calculate.  
 WDS.Calculate
 
 'Assign the fitted model to a variable. See WeibullDataSet.FittedModel. 
 Dim WDSFittedModel as cModel
 WDSFittedModel = WDS.FittedModel
