{title:Description}

{pstd}
{cmd:proportion} produces estimates of proportions, along with standard errors.


{title:Options}

{dlgtab:Model}

{phang}
{opth stdize(varname)} specifies that the point estimates be adjusted by
direct standardization across the strata identified by {it:varname}.  
This option requires the {opt stdweight()} option.

{phang}
{opth stdweight(varname)} specifies the weight variable associated with the
strata identified in the {opt stdize()} option.  The standardization weights
must be constant within the strata identified in the {opt stdize()} option.

{phang}
{opt nostdrescale}
prevents the standardization weights from being rescaled within the
{opt over()} groups.  This option requires {opt stdize()} but is ignored if
the {opt over()} option is not specified.

{phang}
{opt nolabel} requests that value labels attached to the variables in
{varlist} be ignored.

{phang}
{opt missing} specifies that missing values in {varlist} be treated
as valid categories, rather than omitted from the analysis (the default).
