本文对@:AB及其衍变模型进行了分析和总结，提出了直交门槛一般化自回归条件异方差#< 90 8 17C -D@:AB*模型。通过模型平稳性测试、@:效果检定、@:AB效果检定、模型阶数鉴定、模型参数估计与模型诊断对模型进行 评估，作者认为这种模型在估计投资组合资产收益的波动性上优越@:AB及其衍变模型。 (In this paper, @: AB model and its evolution are analyzed and summed up the proposed DC-AC threshold generalized autoregressive conditional heteroskedasticity# < 90 8 17C-D @: AB* model. Smooth adoption of the model testing, @: the effect of test, @: AB test the effect of model order identification, model parameter estimation and model diagnostics to assess the model, the authors suggest that this model portfolios in estimating the volatility of capital gains on the superior @ : AB and its evolution model.)
