This class inherits from the [IClusterModel] class.
A model for mixed data is a mixture model of the form:
$$
f({{x}}_i=({{x}}_{1i}, {{x}}_{2i},\ldots {{x}}_{Li})|\theta)
= \sum_{k=1}^K p_k \prod_{l=1}^L h({{x}}_{li}| \lambda_{lk},\alpha_l).
$$
The density functions (or probability distribution functions)
$$h(.|\lambda_{lk},\alpha_l)$$
can be any implemented model (Gaussian, Poisson,...).
