ARCH GARCH Models Martingale Volatility Finance Market Returns
2010/12/17
ARCH and GARCH models assume either i.i.d. or (what economists lable as) white noise as is usual in regression analysis while assuming memory in a conditional mean square fluctuation with stationary ...
在开展电力零售市场竞争前，销售电价与上网电价的 联动机制是在销售侧正确地反映电力市场供需状况和供电 成本，规避由于发电竞价而引起上网电价波动给电网企业所 带来的市场风险的重要手段。文中通过对电价联动机制存在 的风险进行分析，提出一种考虑用户需求响应的电价联动机 制与建模的新思路。该联动机制中，电价监管者要在一个电 价联动期开始前，向电力5用户公布预期的电价联动水平； 在该联动期结束后，根据实际上网...
在金融时间序列分析中,检验ARCH效果和决定合适的阶是ARCH模型的重要研究主题,在贝叶斯框架下,本文使用贝叶斯因子来检验ARCH效果和选择ARCH模型合适的阶。在路径抽样的基础上,提出了计算ARCH模型贝叶斯因子的方法。最后,我们用一个具体的实例来论证了所提方法的有效性。
