股市中买入时间非常关键,因此,对股市趋势的把握显得至关重要。在高中数学所学习的统计学标准差基础上进行适当的改进,提出一种加权标准差方法,应用到股市趋势分析中,结果表明对股市的中长期趋势预测具有较高的参考价值。
Buying time in the stock market is crucial, so it is crucial to be aware of the stock market trends. Based on the statistical standard deviation of high school mathematics learning, we propose a weighted standard deviation method, which is applied to the stock market trend analysis. The results show that it has a high reference value for the medium- and long-term trend forecast of the stock market.
