Overview
--------

FDFI provides the following main modules:

**Explainers** (:mod:`fdfi.explainers`)
   Core explainer classes for computing feature importance. Includes base
   ``Explainer`` class, specialized explainers (``TreeExplainer``,
   ``LinearExplainer``, ``KernelExplainer``), optimal transport-based
   explainers (``OTExplainer``, ``EOTExplainer``), flow-based DFI
   (``FlowExplainer``), and cross-fitted inference (``Crossfitting``).

**Plotting** (:mod:`fdfi.plots`)
   Visualization functions for feature importance including summary plots, 
   waterfall plots, force plots, and dependence plots.

**Utilities** (:mod:`fdfi.utils`)
   Helper functions for input validation, data sampling, feature name 
   management, and statistical utilities like the ``TwoComponentMixture`` 
   class for variance floor estimation.
