{title:Calculate DFBETAs after {cmd:regress}}


{p 8 15}{cmd:dfbeta2} [{it:varlist}] 
[{cmd:,} {cmdab:D:ouble} {cmdab:CONS:tant}]


{p}{cmd:dfbeta} is for use after {cmd:regress}; see help {help regress}.


{title:Description}

{p}{cmd:dfbeta} will calculate one, more than one, or all the DFBETAs after
{cmd:regress} including the constant term, which can not be obtained by
{cmd:predict} after {help regress} or {help dfbeta}.  The names for the new
variables created are chosen automatically and begin with the letters
{hi:DF}.  The calculated DFBETAs are restricted to e(sample).


{title:Syntax}

{p}{cmd:double} requests the calculated DFBETAs to be stores in double precision.

{p}{cmd:constant} requests the DFBETAs for the constant term to be calculated.
