coefficient 是回归后的系数 不是RSUQARE 202.112.174.* 快试试吧,可以对自己使用挽尊卡咯~ ◆ ◆ R-square 我还以为是回归平方和呢。Regression square sum哈哈! 原来就是决定系数啊 zhangdamingsss 大一新生 1 The numerator of the fraction of r formula issum[(x-mean(x))*(y-mean(y))],an...
R-Square是变量之间相关程度的值。在多元回归分析中，Adj. R-Square根据样本数量和自由度调整后的样本R-Square。考虑了自变量(独立变量)数目的影响。

The Goodness of Fit of Regression Formulae, and the Distribution of Regression Coefficients Other approaches try to minimise the absolute error instead of the mean squared error (like in robust regression). The process of model estimation is, obviously, not a one step task. The assumption......

One thing I do find kind of remarkable is that the Maximum Likelihood R^2 (aka Cox-Snell) isn't just a logical analog - it is the exact same formula for OLS R^2 and Pseudo R^2. That might be why, as Nick says, some may think this is the "obvious" measure. ...
