WeibullGeneralOptions Class

This class describes various settings for WeibullDataSet's GeneralSettings.

Properties

• WarnNegLocation Sets whether a warning will be generated when the location parameter contains a negative value.
• DiscardNegLocation Sets whether to discard the location parameter when it contains a negative value.
• ResetExpLocation Sets 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.)
• Use3PTrueMLE Sets whether to use a true 3-parameter MLE solution for 3-parameter Weibull.
• UseExtendedGGamma Sets whether to allow the lambda parameter of the generalized gamma distribution to take negative values.
• AllowBiasingNormal Sets whether to correct the MLE standard deviation (sigma) value for biasedness (complete data only).
• UsePlottedYPoints Sets 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.

Formatted Usage Example

Declare the WeibullDataSet. See New WeibullDataSet for additional details.

       Dim WDS as New WeibullDataSet

Set various 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
