Detailed Description

Base class (interface) for for general combination of pdfs on discrete support.

Mixtures of Gaussian densities are used internally. Switching to other densities should be trivial.

The merged pdfs are expected to be of the form:

where the resulting merger is a density on . Note that all variables will be joined.

As a result of this feature, each source must be extended to common support

where accumulate variables that were not in the original source. These extensions are calculated on-the-fly.

However, these operations can not be performed in general. Hence, this class merges only sources on common support, . For merging of more general cases, use offsprings merger_mix and merger_grid.

use sources for extensions
