The applicertion of the recognition and prediction of grey correlative pattern in the securities business

According to the grey correlative pattern recognition and the idea that an extended dimension approach from one dimension to multiple dimensions in time series,and considering the defects of the former computation models of the grey correlative degree,we reformed the former computation models and put forward a new computation model of the grey correlative degree: the triangle correlative degree.Boldly perfect the computational steps:qualitative analysis should be done before calculated.Consequently,the defects of the computation models of former correlative degrees had been overcome.Finally,applied the computation model to short forecasting in the securities business,analyzed the result and discovered that the effect of forecasting was very good.
