线性回归(Linear regression) 定义 线性回归(Linear regression)是一种以线性模型假设来拟合自变量与因变量之间关系的方法。通常来说,当自变量只有一个的情况被称为一元线性回归,自变量大于一个的情况被称为多元线性回归。 一元线性回归如下图所示,线性模型由图中直线表示。 基本原理 函数假设:线性函数 损失函数:平方...
I'm trying to add the equation for a linear regression line to a scatter plot that I have made. I first plotted my data points then used the polyfit function to add a first-order line to my plot. Now I want the equation of the line in y = mx + b form to...

SCATTERPLOT的最小規格是一對以括弧括住的變數。 沒有預設規格。 您可以在括弧中指定任意數目的變數配對。 每一組括弧中指定的第一個變數會沿著垂直軸繪製,而第二個變數會沿著水平軸繪製。 繪製符號是用來代表出現在相同位置的多個點。 您可以指定在VARIABLES次指令上指定的任何變數。
A scatter plot is a chart that displays the values of two variables as points. The data for each point is represented by its position on the chart.
SCATTERPLOT的最小指定项是一对括号中的变量。 没有缺省规范。 您可以根据需要在括号中指定任意数量的变量对。 在每组括号中指定的第一个变量沿着垂直轴绘制,第二个变量沿着水平轴绘制。 绘图符号用于表示在同一位置出现的多个点。 可以指定在VARIABLES子命令中指定的任何变量。
