specifies that estimates be computed for multiple subpopulations,
which are identified by the different values of the variables in 
{it:varlist}.

{pmore}
When this option is supplied with a single variable name, such as
{opth over(varname)}, the value labels of {it:varname} are used to identify
the subpopulations.  If {it:varname} does not have labeled values (or there
are unlabeled values), the values themselves are used, provided that they are
non-negative integers.  Noninteger values, negative values, and labels that
are not valid Stata names are substituted with a default identifier.

{pmore}
When {cmd:over()} is supplied with multiple variable names, each subpopulation
is assigned a unique default identifier.

{phang2}
{opt nolabel} specifies that value labels attached to the variables
identifying the subpopulations be ignored.
