Product: STAT
Component: SURVEYMEANS
Title:
Incorrect results for domain analysis with missing values and more than
one stratum
Keywords:
INCORRSTAT INCORROUT DOMAIN STRATA STRATUM MISSING VALUES STANDARD ERROR
VARIANCE MEAN CONFIDENCE LIMITS T P P-VALUE COEFFICIENT VARIATION
In PROC SURVEYMEANS, when STRATA and DOMAIN statements are specified and
there is more than one stratum, if there are missing values for a
continuous analysis variable, then the variance estimation for the mean
and related statistics will be incorrect in the Domain Analysis results
for the domain(s) that have missing values. The incorrect results for
the affected domain(s) include the standard error and variance of the
mean, the confidence limits for the mean, the t statistic and its
p-value, and the coefficient of variation.
To circumvent this problem, use the %SMSUB macro for Version 8.1 which
can be downloaded from our website at the following url:

You may also contact Technical Support to obtain a copy of the macro.
