Ah, yes--the "Standard Error of the Estimate" nomenclature threw
me. The root MSE does not appear to me to be the standard error of
any estimate, but the terminology is obviously different in
political science.
From Wooldridge (2006), p. 107:
"The positive square root of $\hat{\sigma}^2$, denoted $\hat{\sigma}
$, is called the standard error of the regression (SER). The SER
is an estimator of the standard deviation of the error term. This
estimate is usually reported by regression packages, although it is
called different things by different packages. (In addition to
SER, $\hat{\sigma}$ is also called the standard error of the
estimate and the root mean squared error.)"
So, FWIW, it isn't just in political science that one finds the
term "standard error of the estimate": I have seen it in numerous
articles and textbooks on econometrics as well. (Slight apologies
for the LaTeX code, but there is no better way I know of to
indicate math in plain text e-mail messages.)
Hope this helps.
