{title:Description}

{pstd}
{cmd:svy} accepts additional options when performing BRR
variance estimation.


{title:Options}

{dlgtab:SE}

{phang}
{opt hadamard(matrix)} specifies the Hadamard matrix to be used to determine
which PSUs are chosen for each replicate.

{phang}
{opt fay(#)} specifies Fay's adjustment.
The sampling weight of the selected PSUs for a given replicate are multiplied
by {hi:2-}{it:#},
where the sampling weight for the unselected PSUs are multiplied by {it:#}.
{cmd:fay(0)} is the default, and is equivalent to the original BRR method.
{cmd:fay(1)} is not allowed.

{phang}
{opt mse} specifies that {cmd:svy} compute the variance using deviations of
the replicates from the observed value of the statistics based on the entire
dataset.  By default, {cmd:svy} computes the variance using the deviations of
the replicates from their mean.

{phang}
{opt nodots} suppresses the replication dots from being displayed.  By
default, a single dot character is printed for each successful replication;
however, `x' is displayed if {it:command} returns with an error, and `e' is
displayed if one of the values in {it:exp_list} is missing.
