Represents additional results from the life data analysis of an associated WeibullDataSet object.
Properties
| Name | Description |
|---|---|
| CorrelationCoefficient | Gets the correlation coefficient (rho value) if the parameters were estimated using rank regression. Double. |
| LikelihoodValue | Gets the likelihood function value (LK value). Double. |
| PercentNonZero | Gets the percent non-zero (Pnz) value if the data set contains failure at t = 0. Double. A value of 1 indicates that there are no zero failure times in the data set; a decimal value indicates that the data set includes zero failure times. |
Example
The following example demonstrates how to return the correlation coefficient of a particular WeibullDataSet object.
VBA 'Declare a WeibullDataSet object. Dim WDS as New WeibullDataSet 'Add the failure times 10, 20 and 30 to the data set. Call WDS.AddFailure(10, 1) Call WDS.AddFailure(20, 1) Call WDS.AddFailure(30, 1) 'Fit the data to a life distribution, using all default settings. WDS.Calculate 'Retrieve the value of the correlation coefficient. Dim CorrCoeff As Double CorrCoeff = WDS.AnalysisResults.CorrelationCoefficient Msgbox(CorrCoeff)
