{hline}

{pstd}
These are out-of-date commands.

    Rather than typing{col 41}Type
    {hline 29}        {hline 33}
    {cmd:hreg} {it:yvar xvars}{col 41}{cmd:regress} {it:yvar xvars}{cmd:, robust}
    {cmd:hreg} {it:yvar xvars}{cmd:, group(}{it:gvar}{cmd:)}{col 41}{cmd:regress} {it:yvar xvars}{cmd:, cluster(}{it:gvar}{cmd:)}
    {cmd:hreg} {it:yvar xvars} {cmd:[pw=}{it:w}{cmd:]}{col 41}{cmd:regress} {it:yvar xvars} {cmd:[pw=}{it:w}{cmd:]}
    {hline 29}        {hline 33}
{col 41}Note:  {cmd:cluster()} implies {cmd:robust}
{col 48}{cmd:pweight}s implies {cmd:robust}

{pstd}
The same applies to the other h* commands:  use the base command with options
{cmd:robust} and {cmd:cluster()}.

{pstd}
The only difference is that the new {cmd:robust} option applies a
degree-of-freedom correction to the VCE that the old h* commands did not.
{cmd:robust} is better.
