摘要 文章针对ARCH模型参数传统估计方法的不足,提出了利用量子粒子群算法的改进算法,并利用此算法实证建立了美国证券市场道琼斯指数收益的ARCH模型,更加精确地动态度量了证券市场收益序列的条件“异方差”,进行了指数走势预测。 In this paper,quantum-behaved particle swarm optimization algorithm is developed for some serious disadvantages of traditional estimating methods of ARCH,and the ARCH model for Dow-Jones average stock return are established empirically,finally forecast of the return is given,
