Regression with Huber variance estimates                        (STB-13:  sg17)
----------------------------------------

	^hreg2^   [depvar [indepvars] [weight] [^if^ exp] [^in^ range] ] 
		[^, g^roup^(^varname^)^ regress_options ]


^pweight^s, ^aweight^s, ^fweight^s, and ^iweight^s are allowed.

^hreg2^ shares the features of estimation commands; see [4] estimate.

To reset problem-size limits, see ^help matsize^.


Description
-----------

Please see ^help hreg^ or [5s] huber for a complete description of the purpose
of Huber variance estimates.  ^hreg2^ performs the same estimation as ^hreg^ except
that the small sample adjustment described by Rogers (1993) is made.
