When is it Appropriate to Use/Trust the Distribution Wizard?

A prior HotWire article described how to use the Distribution Wizard in Weibull++. It explained how the Distribution Wizard ranks the various selected models to determine which possible model fits the data the best. It also discussed how each model is analyzed using three methodologies, the Kolmogorov – Smirnov (K-S) Test, a normalized correlation coefficient and the likelihood value associated with the best fit parameters from a maximum likelihood analysis. This is followed by each model being ranked based on each method and a final model ranking being generated from the combination of the individual rankings.


In this article, we review several different data sets, analyze them using the Distribution Wizard and then discuss whether the model suggested by the Distribution Wizard is appropriate to use.
