With Dsem Analog Simulation Stock Market Discussion

With the development of science and technology micro-economics has been developed greatly. Using various new tools and theories, people has furthered researches on market behavior. The stock market is famous for its quality of hard-describing hard-analyzing and hard-anticipating. At present is famous for its quality of hard-describing, hard-analyzing and hard-anticipating. At present, the existing theories including the efficient market theory, theory of optimal price, etc. However, these theories have many inadequacies in terms of practical maret. First, there is no specific parameter for quantization; second, the effects of transaction fee are ignored; Third, because these models are equilibrium models, they can't reveal many of the prosperities observed in empirical markets, such as fat-tails, long-range correlations in volatility, etc.In the process of I study financial economics, when the teacher Xu jia-gen to speak the price of the stock market to visit the distance examination and the artificial intelligence models, I think, if mathematics combines with the calculator.(I studied mathematics four years in the southwest Normal University).The stock market price exercise regulation will easily confidence.I set out from the basic thought of the ARCH model, some at that time engrave the occurrence of news voice is to obey the positive normal distribute. The average number that positive normal distribute is zero, the square number to at any time is a the quantity of a variety. And this at any time the square number of a variety is the line combination that is the limited item news number's square. Thus, it constituted from return to return the condition difference square number model. From this basic thought we can see, because of the square number of now time news voice is the limited item square number to returned to return in the past, It's means that the motion of the news voice have the certain memory, therefore, if in past every moment the square number of the news voice differed to become big, so the square number of the news voice differed to usually also come after it to...
