MLQuantify Methods
==================

The table below lists all the quantification methods available in the ``mlquantify`` library, their references, multiclass support, and type (aggregative, meta, or non-aggregative).

.. note::
   In ``binary`` classification problems, methods that do not natively support multiclass classification (marked ``No`` in the ``Multiclass`` column) remain applicable through standard reduction strategies like **one-vs-rest** or **one-vs-one**.
