WeibullGeneralOptions Class

Member of: SynthesisAPI

Represents miscellaneous analysis settings for an associated WeibullDataSet object.

Properties

Name	Description
AllowBiasingNormal	Indicates whether to correct the MLE standard deviation (sigma) value for biasedness (applies to complete data only). Boolean.
DiscardNegLocation	Indicates whether to discard the location parameter when it contains a negative value. Boolean.
ResetExpLocation	Indicates whether to reset the value of the location parameter equal to the first failure time, T1, if the parameter is greater than T1. (Exponential distribution only.) Boolean.
Use3PTrueMLE	Indicates whether to use a true 3-parameter MLE solution for 3-parameter Weibull. Boolean.
UseExtendedGGamma	Indicates whether to allow the lambda parameter of the generalized gamma distribution to take negative values. Boolean.
UsePlottedYPoints	Indicates whether to use the plotted points (using median ranks or Kaplan-Meier) to calculate the difference between observed and model estimated probability for the Kolmogorov-Smirnov test. Boolean.
WarnNegLocation	Indicates whether a warning will be generated when the location parameter contains a negative value. Boolean.

Example

The following example demonstrates how to initialize the settings for a particular WeibullDataSet object.

VBA

 'Declare a new WeibullDataSet object. 
  Dim WDS As New WeibullDataSet
 
 'Specify the settings. 
  WDS.GeneralSettings.AllowBiasingNormal = False
  WDS.GeneralSettings.DiscardNegLocation = False
  WDS.GeneralSettings.ResetExpLocation = True
  WDS.GeneralSettings.Use3PTrueMLE = False
  WDS.GeneralSettings.UseExtendedGGamma = False
  WDS.GeneralSettings.UsePlottedYPoints = False
  WDS.GeneralSettings.WarnNegLocation = False

 'Add failure times to the data set. 
  Call WDS.AddFailure(100, 1)
  Call WDS.AddFailure(120, 1)
  Call WDS.AddFailure(130, 1)  

 'Analyze the data set. 
  WDS.Calculate()

VB.NET

 'Declare a new WeibullDataSet object. 
  Dim WDS As New WeibullDataSet
 
 'Specify the settings. 
  WDS.GeneralSettings.AllowBiasingNormal = False
  WDS.GeneralSettings.DiscardNegLocation = False
  WDS.GeneralSettings.ResetExpLocation = True
  WDS.GeneralSettings.Use3PTrueMLE = False
  WDS.GeneralSettings.UseExtendedGGamma = False
  WDS.GeneralSettings.UsePlottedYPoints = False
  WDS.GeneralSettings.WarnNegLocation = False
 
 'Add failure times to the data set. 
  WDS.AddFailure(100, 1)
  WDS.AddFailure(120, 1)
  WDS.AddFailure(130, 1)  

 'Analyze the data set. 
  WDS.Calculate()
