Detailed Description

Main interface class to the generic discriminator computer framework.

The MVAComputer class represents an instance of the modular discriminator computer. It is constructed from a "calibration" object which contains all the required histograms, matrices and other trainina data required for computing the discriminator. The calibration data also defines the names and properties of variables that can passed to that instance of the discriminator computer. The evaluation methods then calculates the discriminator from a applicable set of input variables, i.e. vector of key-value pairs.
