Next we use some of the outreg options.
. outreg weight weight2 using outregl, se bdec(4) bfmt(e) tdec(3) nonotes replace
. ’more outregl.out
Mileage (mpg)
Weight (lbs.) -1.6573e-02
(3.9692e-03)**
weight2 1.5912e-06
(6.2489e-07)*
Constant 5.6539e+01
(6.1974e+00)**
Observations 74
R-squared 0.691
Finally, here is an example I used in my research which investigates the relationship of a dependent variable y on four X
variables and shows how outreg can be used to produce the kinds of tables needed in publications.
. regress y xl-x2
. outreg using table4, title(,,Three Regression Variants”)
> addnote("", ’’Run at $S_TIME, $S_DATE”, Using data from $S_FN) replace
. regress y xl-x3
. outreg using table4, append
. regress y xl x3-x4
. test x3 x4
. outreg using table4, append addstat(,'F test, χ3=x4=0,', r(F), Prob > F, r(p)) adec(2,3)
. type table4.out

Abstract: The command clad for estimating Powell’s (1984) censored least absolute deviations estimator and bootstrap estimates
of its sampling variance is introduced and illustrated.
Keywords: censored least absolute value deviations estimator, bootstrap.
