```HI,

Is it possible to use outreg2 command with test?

following is what i have to repeat for 10 variables and 10 years.

. ttest vw1edf1dec if year == 1999, by(allheg09)

Two-sample t test with equal variances

diff = mean(Non Hedg) - mean(All Hedg)                        t =

Ho: diff = 0                                     degrees of freedom =

Pr(T < t) = 0.1867         Pr(|T| > |t|) = 0.3734          Pr(T > t) =
0.8133

. return list

scalars:
r(sd) =  1.112888555684657
r(sd_2) =  1.166173558360495
r(sd_1) =  .3496573923198343
r(se) =  .1928791248423141
r(p_u) =  .8133246313731823
r(p_l) =  .1866753686268177
r(p) =  .3733507372536353
r(t) =  -.8912968435767951
r(df_t) =  369
r(mu_2) =  .3556845056082674
r(N_2) =  334
r(mu_1) =  .1837719504444583
r(N_1) =  37

.

i want to use only few items e.g.  r(N_1), r(N_2), r(mu_1),r(mu_2)
in outreg2 it says that i can use scalars but i don't know how to use.

i tried following but it gave me output of regression.
