RE: st: RE: matrix results saved

[Nick Cox <n.j.cox@durham.ac.uk>]

Use -display-. If you have a matrix, you can display any element of it using -display-. 
For your problem, you may want to specify extra text (which could be spaces), a format, etc. using -display-. 

. matrix a = 1

. mat li a

symmetric a[1,1]
    c1
r1   1

. di a[1,1]
1

. di "interesting number is "  %4.3f a[1,1]
interesting number is 1.000

Sorry Nick for not being so explicit.

What I want is that these two values r1  22.942303 (chi2 statistic
saved as a matrix) and r1  .02821978 (p-value) appears below the
estout results already saved. An example of this with my first
regression:

estout, cells(b(star fmt(%9.3f)) se(par)) stats(r2_a N hettest hetp,
fmt(%9.3f %9.0g %9.3f %9.3f)):

                     Reg1
----------------------------
sap                -0.238
                  (0.183)
liqmk               1.183**
                  (0.350)
----------------------------
r2_a                0.370
N                      54
hettest            32.227
hetp                0.152
bg                  22.942303
pbg                  0.02821978
