The SURVEYREG Procedure

Root Mean Square Errors

PROC SURVEYREG computes the square root of mean square errors as

\[  \sqrt {\mbox{MSE}} = \sqrt {n ~  \mbox{SS}_\mathit {error} ~  / ~  (n-p) ~  w_{\cdot \cdot \cdot } }  \]

where $w_{\cdot \cdot \cdot }$ is the sum of the sampling weights over all observations.
