Abstract :
That is a good way that use the ARCH family models to describe the time-varying characteristic of the return sequence on stocks. Intuitively, the influence to present from the long history data should not bigger than the short history data. So the order restriction to the parameter is according to the fact better. This paper researched the maximum likelihood estimator (MLE) of the parameters in the β - ARCH(0,q) model under the nonnegative restriction. At last we use the model in Chinese stock market.
