{cmd:normalden(}{it:z}{cmd:,}{it:s}{cmd:)} returns the rescaled standard
        normal density.  {cmd:normalden(}{it:z}{cmd:,}{it:s}{cmd:)} =
        {cmd:normalden(}{it:z}{cmd:)}/{it:s} if {it:s}>0 and {it:s} not
        {it:missing}, otherwise, the result is {it:missing} ({hi:.}).{p_end}

{cmd:normalden(}{it:x}{cmd:,}{it:m}{cmd:,}{it:s}{cmd:)} returns the
	normal density with mean {it:m} and standard deviation {it:s}.

	{cmd:normalden((}{it:x}-{it:m}{cmd:)/}{it:s}{cmd:)/}{it:s} if {it:s}>0,
