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.
