Bayesian Time-Varying Quantile Forecasting for Value-at-Risk in Financial Markets
用于金融市场风险价值预测的贝叶斯时变分位数模型
Recently, advances in time-varying quantile modeling have proven effective in financial Value-at-Risk forecasting. Some well-known dynamic conditional autoregressive quantile models are generalized to a fully nonlinear family. The Bayesian solution to the general quantile regression problem, via the Skewed-Laplace distribution, is adapted and designed for parameter estimation in this model family via an adaptive Markov chain Monte Carlo sampling scheme.
