What is the feature?

  • Makes the Dirichlet linear multinomial available for the power user. Wrapper functions currently can't accommodate anything other than multinomial.

How have you implemented the solution?

  • Implemented the Dirichlet linear multinomial in the backend code.

Does the PR impact any other area of the project, maybe another repo?

  • no

Removed comment about using the FIMS custom sum function.
Removed unnecessary include for fims_vector.hpp.
…test inputs for DM PMF read from csv created and verified with "Test_value_diric_multinom.R"
Use the global lgamma (::lgamma) in ddiric_multinom to avoid incorrect fims_math resolution, and update calls accordingly. Add fims_math include to the Dirichlet-multinomial functor and export the functor header from distributions.hpp. Fix Rcpp distribution interface bugs and naming/initialization issues: correct make_shared/copy-constructor types for the DDirichletMultinomial interface, initialize the underlying theta from initial_value_m, and update Rcpp bindings (method names, fields and expose theta). These changes address compilation/runtime errors and ensure the Dirichlet-multinomial distribution is properly registered and usable from R.
Export DDirichletMultinomDistribution in NAMESPACE to make the new distribution available to package users. Also add DDirichletMultinomialDistributionsInterface to inst/WORDLIST so the identifier is recognized by the package wordlist (avoids spellcheck/lint issues).
Added 'dirichlet_multinomial' to available distributions and created a new function for it.
Updated documentation @details to clarify the implementation of the Dirichlet-multinomial log-probability mass function.
…roposed fix to switch between composition distribution types in "fix_helper_setup_R1.docx". More general solution recommended for multiple composition types and other submodel components.
…ration-tests-validation.R to support Dirichlet-Multinomial distribution.
