But that's an OLAP application, not a spatial application.
When evaluating treatment efficacity, it is appropriate to use a statistical package to perform linear regressions, ANOVA, with all of the corresponding T- and F-tests. None of which has anything to do with there being (or not being) spatial operators in Oracle.
A distance operator in the database is not the same thing as a linear regression.
For ANOVA, do a database query and extract the information into SAS or some similar tool. Spatial coordinates don't replace external tools such as SAS.
