There are many options for the ways in which these tests can applied, so many that evaluation by randomised controlled trials is problematic. Modelling gives an alternative method for evaluation. At first sight, one might expect that such evaluation might be amenable to analysis using decision tree methods however we have opted to use alternative methods, based on elementary probability, which allow a wider range of issues to be examined. _____________________________________ ----------- Dr. T.J.
