"""Filtering algorithms for Dynamic Factor Stochastic Volatility (DFSV) models.

This module provides implementations of various filtering algorithms including:
- Bellman Information Filter (BIF)
- Bellman Filter (covariance form)
- Particle Filter (Bootstrap/SISR)

All filters inherit from the common DFSVFilter base class.
