{title:Description}

{pstd}
{cmd:expand} replaces each observation in the current dataset with n
copies of the observation, where n is equal to the integer part of the
required expression.  If the expression is less than 1 or equal to
{it:missing}, it is interpreted as if it were 1, and the observation is
retained but not duplicated.
