SELECTION.Selection statistics.This option includes Akaike information criterion (AIK), Ameniya’s prediction criterion (PC), Mallows conditional mean squared error of prediction criterion (Cp), and Schwarz Bayesian criterion (SBC)2. The statistics are displayed in the Model Summary table....
Note that the variance-covariance matrix of the estimator is directly proportional to the error variance, which is unknown. We can estimate the error variance using the mean squared error: σ^>2ε=1n−p(Y−Xβ^)′(Y−Xβ^).σ^>ε2=1n−p(Y−Xβ^)′(Y...
The root mean squared error (RMSE) of calibration of 42 g/d represents only 10% of the overall daily CH4 production, which is 23 g/d lower than the RMSE for the SF6-based equation. During the external validation step an RMSE of 62 g/d was observed. When the RC equation was applied...
One may not therefore assume the validity of the equations for very high density of field and matter, and one may not conclude that the 'beginning of the expansion' must mean a singularity in the mathematical sense. All we have to realise is that the equations may not be continued over ...

The error sum of squares (ESS) is defined as y y−2bX y+b X Xb. The model sum of squares (MSS) equals TSS − ESS. The degrees of freedom is k − c. The mean squared error, s2, is defined as ESS/(n − k) if small is specified and ESS/n otherwise. The root mean ...

(I adopt this apparently unwieldy notation because Ihave found that students frequently confuse squared amplitudes and mean square values, leading to an error of a factor of two.) By setting A˜ to a + jb and B˜ to c + jd, you may show that the mean square pressure is real, ...
