求助!R语言中,从回归结果中,怎么求MSE是误差方差啊。两者我都混了。比如这个回归结果:
Call:
lm(formula = V2 ~ V4, data = ab1)
Residuals:
Min 1Q Median 3Q Max
-4.1887 -1.0713 -0.3449 0.6822 6.2617
Coefficients:
Estimate Std. Error t value Pr(>|t|)
(Intercept) 4.5379 1.5852 2.863 0.008193 **
V4 1.3477 0.3159 4.267 0.000233 ***
---
Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1
Residual standard error: 2.086 on 26 degrees of freedom
Multiple R-squared: 0.4118, Adjusted R-squared: 0.3892
F-statistic: 18.2 on 1 and 26 DF, p-value: 0.0002326
