WeibullAnalysisResults Class

Member of: SynthesisAPI

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

VBA

 'Declare a WeibullDataSet.  
  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)
