Sets some of the Application Setup calculation options that can apply to both the Calculate and CalculateBestFit methods.
In Weibull++, these settings can be found on the Calculations page of the Application Setup window.
Properties
Special Options on Location Parameter
- WarnNegLocation (type: boolean) Sets whether a warning will be generated when the location parameter contains a negative value.
- DiscardNegLocation (type: boolean) Sets whether to discard the location parameter when it contains a negative value.
- ResetExpLocation (type: boolean) 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 (type: boolean) Sets whether to use a true 3-parameter MLE solution for 3-parameter Weibull.
- UseExtendedGGamma (type: boolean) Sets whether to allow the lambda parameter of the generalized gamma distribution to take negative values.
Other Options
- AllowBiasingNormal (type: boolean) Sets whether to correct the MLE standard deviation (sigma) value for biasedness (complete data only).
- UsePlottedYPoints (type: boolean) 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.
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
