Raskin say they are using, a more statistically accepted procedure is to calculate a score using a quadratic discriminant function.

4.  

A proper Bayesian calculation would be far more elaborate and might produce markedly different results.

5.  

The distinctions made regarding the logistic regression and discriminant analysis methods used by the two systems are not especially cogent for present purposes.
