Class Multinomial.Estimator

  • All Implemented Interfaces:, java.lang.Cloneable
    Direct Known Subclasses:
    Multinomial.MAPEstimator, Multinomial.MEstimator
    Enclosing class:

    public abstract static class Multinomial.Estimator
    extends java.lang.Object
    implements java.lang.Cloneable,
    A hierarchy of classes used to produce estimates of probabilities, in the form of a Multinomial, from counts associated with the elements of an Alphabet. Estimator itself contains the machinery for associating and manipulating counts with elements of an Alphabet, including behaving sanely if the Alphabet changes size between calls. It does not contain any means of generating probability estimates; various means of estimating are provided by subclasses.
