4. 绘制散点图:为了更直观地展示回归分析的结果,可以使用scatter函数绘制散点图。例如,可以使用以下代码绘制散点图: figure; scatter(data(:,1), data(:,2)); title('Regression Analysis'); xlabel('X'); ylabel('Y'); 通过以上步骤,可以完成MATLAB中的regress函数实现回归分析。 点...
回归分析 (英语:Regression Analysis) 是一种统计学上分析数据的方法,目的在于了解两个或多个变量间是否相关、相关方向与强度,并建立数学模型以便观察特定变量来预测研究者感兴趣的变量。更具体的来说,回归分析可以帮助人们了解在只有一个自变量变化时因变量的变化量。一般来说,通过回归分析我们可以由给出的自变量估计因...
