R - 回归分析(Regression Analysis) 回归分析是数据集分析中的首选工具之一,用于估计变量之间的关系,通常可以让你立即获得数据结构的信息。 - 《R for Data Science》- Dan Toomey 简单回归 简单线性回归就如其名:是一种非常简单的简单线性方法,用单个预测变量X预测响应变量Y。它估计X和Y近似成线性关系用,数学上...
R-squared Is Overrated! When you ask, “How high should R-squared be?” it’s probably because you want to know whether your regression model can meet your requirements. I hope you see that there are better ways to answer this than through R-squared!
val lr : LinearRegression = new LinearRegression() .setFitIntercept(true) //是否使用偏置项参数 .setLoss("squaredError") //损失函数,这里使用均方误差 .setSolver("l-bfgs") //优化算法,这里使用l-bfgs .setStandardization(true) //训练数据标准化 ...

Low R-Squared vs. High R-Squared Value One misconception about regression analysis is that a low R-squared value is always a bad thing. This is not so. For example, some data sets or fields of study have an inherently greater amount of unexplained variation. In this case, R-squared ...
