[contingencies]

It exceeds my mathematical knowledge, and I gave up trying to read it. My inference was "use of some kind of transformed space when modelling distribution" but the benefit/result versus a direct analysis was absolutely a mystery.

I would still love an explanation of the practical benefits of its use (preferably without the use of numbers or formulae) and IMHO this is what Wikipedia should present. If anyone here is are able to write that description, please do.
