random group variance estimation of the mean for survey data
------------------------------------------------------------------------------
^ranvar^ varlist [aweight] [if]
^ranvar2^ varlist [iweight] [if]
Description
-----------
^ranvar^ calculates the random group variance estimator of the mean for survey
data. The estimator is described in detail by Wolter (1985) "Introduction to
Variance estimation", New York/Berlin (Springer). This estimator is an
alternative to other estimators of the variance of sample statistics
for survey data e.g. the jacknife or taylor linearization. The
application of the random group estimator requires, that random groups
are already defined during data collection.
Note: ^iweight^ is available with ^ranvar2^.
Note for ^SOEP^ Users: The estimation is described in K.4
