基于模糊技术的期货价格预测模型

期货价格风险一直是期货市场风险控制研究的中心和重点．结合模糊控制理论，将其引入期货价格风险问题研究中．基于遗传算法和模糊IF—THEN规则，建立适合期货价格预测的模型．在实证分析基础上，利用ANFIS，对模型进行学习和测试．实验结果表明，该模型能较准确地预测我国铜期货价格的波动趋势．     

基于Volterra-Wiener-Korenberg模型的亚洲6种汇率非线性特征研究

基于Volterra-Wiener-Korenberg(VWK)模型非线性检验方法对亚洲6种汇率时间序列进行了非线性动力学特征研究,并结合替代数据分析检验了该方法在汇率时间序列领域统计结果的有效性.结果表明通过比较原始数据和基于原始数据所产生的替代数据之间的差异度,零假设在95%置信度范围内被拒绝,基于VWK模型非线性检验方法能够有效地检验出6种汇率的非线性特征,且这6种汇率呈现出内在的确定性非线性结构.     

Testing for Nonlinearity in Five Emerging Markets'' Exchange Rates

Unlike the Brock,Dechert,and Scheinkman(BDS)test,the Surrogate Data method is not only able to provide a nonlinearity test for exchange rates,but also distinguish whether the nonlinear features come from the economic system itself.Our analysis gives some evidence on the presence of nonlinear dependency of five emerging markets' exchange rates by using BDS test.Furthermore,we present evidence in existence of intrinsic and deterministic nonlinearity in the five exchange rates using the Surrogate Data method,c...
