Univariate Volatility Models ---------------------------- ``arch.univaraite`` provides both high-level (:func:`~arch.univariate.arch_model`) and low-level methods (see :ref:`mean-models`) to specify models. All models can be used to produce forecasts either analytically (when tractable) or using simulation-based methods (Monte Carlo or residual Bootstrap). .. module::arch.univariate .. toctree:: :maxdepth: 1 Introduction Examples Forecasting Forecasting Examples Forecasting Scenarios Mean Models Volatility Processes Using the Fixed Variance Process Distributions Results Utilities Background and References
