9 февр. 2015 г. · I am trying to figure out what is the estimated variance (ie the estimated error) of residuals around a fitted line. |
9 сент. 2020 г. · Variance can only be calculated around a parameter, and it is the summed deviations from that (or those) parameters divided by the degrees of freedom. |
5 мая 2020 г. · With var(X1)=var(X2)=var(X3)=s2R, the residual variance. We can deduce that var(m1) ... |
