#include <itkMixtureModelComponentBase.h>
base class for distribution modules that supports analytical way to update the distribution parameters
This class expects that its subclasses (distribution components) should have analytical expressions for updating its parameters using only the measurement vectors and their associated weights.
This class can be considered as a macro class that encapsulates the storage for the weights, model (subclasses of MembershipFunctionBase), and model parameter estimators (implementation of analytical expressions).
Subclasses of this class should define their own distribution specific membership function. For example, GaussianMixtureModelComponent class defines and creates a GaussianDensityFunction object for that matter. Subclasses should also cast such membership function object to MembershipFunctionBase object. By doing that, users can get pointers to membership functions from different distributional model
