SimpleLinearRegression 类使用最小二乘法准则推导出 Y 轴截距(Y Intercept)和斜率(Slope)参数的估计值。这些估计的参数用来构造线性方程(请参阅 清单 3),该方程对 X和 Y值之间的关系进行建模。 使用推导出的线性方程,您就可以得到每个 X值对应的预测 Y值。如果线性方程与数据非常吻合,那么 Y的观测值与预测值...
简单线性回归(Simple Linear Regression) 1 很多做决定过过程通常是根据两个或者多个变量之间的关系 2 回归分析(regression analysis)用来建立方程模拟两个或者多个变量之间如何关联 3 被预测的变量叫做:因变量(dependent variable), y, 输出(output) 4 被用来进行预测的变量叫做: 自变量(independent variable), x, 输...
In this article we will show how to use Excel to generate data from a simple linear regression model and illustrate how the statistical methods behave both when the fundamental assumptions of the model hold and when the fundamental assumptions are violated. The advantage of the using the program...
This is certainly possible. If you are using simple linear regression, then the p-value being so low only means that there is a significant difference between the population correlation and zero. It doesn’t mean that the population value of r is high; it just means that it is not likely...
