Description: 数据预测算法，主要是一元n次方程的回归预测实现。* 预测分析--本算法只适用于有明显线性趋势的数据 * 默认为一元二次曲线方程法 * * 本程序主要涉及有两个算法 * 1．用最小二乘原理找到线性方程组的系数和常数。 * 2．解线性方程组 * 本程序在解线性方程组中，由于考虑到收敛性问题未采用迭代法，而是采用Gauss-Jordan消去法来解决。-data prediction algorithm is mainly one yuan n equation forecast to achieve reunification.* Forecast and Analysis-- This algorithm applies only to clear linear trend data* default as a quadratic curve equation method** The procedure involves two main algorithm* 1. Using the principle of least squares linear equations to find the constants and coefficients.* 2. The solution of linear equations* The procedure for solving linear equations, due to convergence problems using iterative method, instead of using the Gauss-Jordan elimination method to solve.

Description: 股票的价格随着时间会在一定范围内波动，对于每个股票，股民需要三种报告：股票的当前价格；股票价格的统计分析报告（最低价、最高价、均价）；股票价格趋势预测（建议采用移动平均预测法）。根据实际情况，也可能需要增加其他类型的报告。提示：股价变动用随机数模拟：java.util.Random。代码运用观察者模式，编写了上述股票行情程序，当股票价格变动时，实现各种报告的更新。-The price of the stock will over time in a certain range, for each stock, investors need to three report: the current price of stock Stock price statistics analysis report (the lowest price, maximum price, average price) Stock price trend prediction (recommended moving average prediction method). According to actual condition, also may need to increase the other types of reports. Tip: share price changes with Random simulation: Java. Util. Random. Code using spectator mode, write the stock market program, when the stock price changes, realize all kinds of report of updates.
