Description

This class inherits from the [IClusterModel] class. A gamma mixture model is a mixture model of the form:

f({x}|\boldsymbol{θ}) \\ =∑_{k=1}^K p_k ∏_{j=1}^d γ(x_j;a_{jk},b_{jk}) \\ \quad {x} \in {R}^d.

Constraints can be added to the shapes and/or scales in order to reduce the number of parameters.
