272Base class for general combination of pdfs on discrete support.
273<p>
274Mixtures of Gaussian densities are used internally. Switching to other densities should be trivial.<p>
275The merged pdfs are expected to be of the form: <p class="formulaDsp">
276<img class="formulaDsp" alt="\[ f(x_i|y_i), i=1..n \]" src="form_124.png">
277<p>
278 where the resulting merger is a density on <img class="formulaInl" alt="$ \cup [x_i,y_i] $" src="form_125.png"> . Note that all variables will be joined.<p>
279As a result of this feature, each source must be extended to common support <p class="formulaDsp">
280<img class="formulaDsp" alt="\[ f(z_i|y_i,x_i) f(x_i|y_i) f(y_i) i=1..n \]" src="form_126.png">
281<p>
282 where <img class="formulaInl" alt="$ z_i $" src="form_127.png"> accumulate variables that were not in the original source. These extensions are calculated on-the-fly.<p>
283However, these operations can not be performed in general. Hence, this class merges only sources on common support, <img class="formulaInl" alt="$ y_i={}, z_i={}, \forall i $" src="form_128.png">. For merging of more general cases, use offsprings merger_mix and merger_grid. <hr><h2>Member Function Documentation</h2>
