Description: Estimation, simulation, hypothesis testing, AR-order selection,
    and forecasting for univariate higher-order stochastic volatility SV(p)
    models. Supports Gaussian, Student-t, and Generalized Error Distribution
    (GED) innovations, with optional leverage effects. Estimation uses
    closed-form Winsorized ARMA-SV (W-ARMA-SV) moment-based methods that
    avoid numerical optimization. Hypothesis testing includes Local Monte
    Carlo (LMC) and Maximized Monte Carlo (MMC) procedures for leverage
    effects, heavy tails, and autoregressive order. AR-order selection is
    also available via information criteria (BIC/AIC) using the Kalman-filter
    quasi-likelihood and the Hannan-Rissanen ARMA residual variance.
    Forecasting is based on Kalman filtering and smoothing. See Ahsan and
