Hausdorff Distance

    I was trying to think of some different ways of highlighting similar sets of data in QlikView & under 'similarity metrics' found Hausdorff Distance in an old text book I have (, although I found a more comprehensible write up on the web here,


    In scripting the calculation actually drops out quite neatly, so I have attached sample using some data I found on a resource for teachers in New Zealand;


    I am not sure anything particularly insightful drops out of that particular set of data & wonder if something built in to QlikView would show similar relationships, or that scripting (rather than being calculated on the fly, depending on selections) limits it, but I think an interesting concept.
