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. Default value = False. |
| DiscardNegLocation | Indicates whether to discard the location parameter when it contains a negative value. Boolean. Default value = False. |
| 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. Default value = True. |
| Use3PTrueMLE | Indicates whether to use a true 3-parameter MLE solution for 3-parameter Weibull. Boolean. Default value = False. |
| UseExtendedGGamma | Indicates whether to allow the lambda parameter of the generalized gamma distribution to take negative values. Boolean. Default value = True. |
| 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. Default value = True. |
| WarnNegLocation | Indicates whether a warning will be generated when the location parameter contains a negative value. Boolean. Default value = False. |
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()
