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()
