TheMean Squared Error (MSE)is an estimate that measures the average squared difference between the estimated values and the actual values of a data distribution. In regression analysis, the MSE calculates the average squared differences between the points and the regression line. That is, the mean...

Inregression analysis, the term "standard error" refers either to the square root of thereduced chi-squared statisticor the standard error for a particular regression coefficient (as used in, say,confidence intervals). 标准误,也就是标准误差,其实就是对某统计量参数\beta_k的标准差的估计值(estimate...
回归分析(regression analysis)是确定两种或两种以上变量间相互依赖的定量关系的一种统计分析方法,可以通过分析一定的趋势来进行预测。 最简单的例子是:y = ax+ b,计算在坐标系上的点的坐标,通过最小二乘法计算,找到一条直线来描述两个变量间的关系。 如下图,统计披萨的尺寸和价格,得出一条直线,呈正相关,可以得...

In regression scenarios, MSE and MAE offer different perspectives on predictive accuracy, with MSE penalizing larger errors and MAE providing a more robust evaluation that is insensitive to outliers. The appropriate choice of evaluation metrics is essential for model selection, optimization, and ...
