If you insist on doing this by hand, try:

*********
cap ssc inst indeplist
di in red _rc

sysuse auto, clear
reg p w rep g tr
qui indeplist

qui foreach indep in `r(X)'{
noi di in red "Independent Var: `indep'"
noi di in red "t-stat:" %5.4fc _b["`indep'"]/_se["`indep'"]
noi di in red "p-value: " %5.4fc 2*ttail(e(df_r),abs(_b["`indep'"]/_se["`indep'"])) _n(2)
}

di in red "Constant"
di in red "t-stat:" %5.4fc _b[_cons]/_se[_cons]
di in red "p-value: " %5.4fc 2*ttail(e(df_r),abs(_b[_cons]/_se[_cons])) _n(2)
********

Well, I guess Mr Cox idea is quite good and efficient enough. I will be looking at your links later on.
thanks!

But having obtained the t-value, is there also a way to calculate/extract the corresponding p-value?

BTW, your -gen- statement is probably not the most expedient way to
achieve
what I assume you want. You might want to look into -local-s or -scalar-s
for more efficient storage. Or indeed -ssc d parmest- which simplifies
this
task greatly...

Subject: st: extract t-values

Hi Stata users,

does anybody know a ansver to this problem:

I want to extract the t-values from the table displayed below. To obtain
the
coefficients is easy by programming gen coef1=_b[var1]

Is there also a command to extract the t-value of var1???
