Here is an analysis performed by statisticians from the Province of British Columbia, Fraser Health, Population Health Observatory utilizing SAS rather than SPSS which is the best example of this approach. In this technical research note it outlines very nicely the approach taken that can be utilized by other regulatory scientists and licensing researchers. I highly recommend the statistical approach.
