WeibullDataSet.CalculateBestFit

Performs goodness of fit tests to find the distribution that best fits the data set. Returns a message box that shows the estimated parameters of the distribution that best fits the data. (Similar to the Distribution Wizard feature in Weibull++). Use the  property of the class to specify the criteria for evaluating the fit.

In addition, the method automatically creates a retrievable cModel object that represents the fitted model from the life data analysis.
