{title:Description}

{pstd}
{opt fillin} adds observations with missing data so that all interactions
of {varlist} exist, thus making a complete rectangularization of
{it:varlist}.  {opt fillin} also adds the variable {opt _fillin} to the
dataset.  {opt _fillin} is 1 for observations created by using {opt fillin}
and 0 for previously existing observations.
