IClusterModelBase: Interface base Class [IClusterModelBase] for Cluster models.
Description
This class encapsulate the common parameters of all the Cluster models.
Arguments
Details
A Cluster model is a model of the form
$$f({x}|\boldsymbol{\theta})
\sum_{k=1}^K p_k h({x};\boldsymbol{\lambda}_k,\boldsymbol{\alpha})
\quad {x} \in J.$$
where h can be either a pdf, a discrete probability, (homogeneous case)
or a product of arbitrary pdf and discrete probabilities (heterogeneous case).
