I will take this opportunity to rant a bit.

If one has specified the significance level a priori and done only the
single test, a p-value of 0.05 means the usual:  a result this extreme
or more so will occur 5% of the time.

However, most studies (rightfully) explore other variables and conduct
many tests of hypotheses.  These are suggested by the data and the
conventional meaning of significance no longer holds.  

In my analyses, I will do such tests, but I expect a much lower
(p<<0.05) level before I get excited.  It's important to recognize that
these analyses are exploratory.

Some statisticians will disagree and state that multiple testing is not
an issue.

Note the rampant grade inflation then! Even in the environmental
sciences, fields known for ornery systems and oddball scientists, P ~
0.1 would not be taken as anything other than a weak indication.

Omit the -star- option in the -esttab- call and you do get this standard
behavior as in the Stata command - estimates table-. But my experience
in
the economics profession shows me that one star for ten percent is now
quite
common...

Nick Cox

Note the grade inflation: hereabouts * implies a P-value at most 0.05. 

P.S. -outreg2- is a user-written program on SSC.

I have  installed the updates for *outreg2*. 

I have a regression model like:

reg dep_var ind_var1 ind_var2, robust

After entering this command in stata, I obtained the standard stata
regression table (I guess you what I mean)

Now, I want to put my results into MS EXCEL and I want to mark the
coefficients with the widely known signs like *, **, *** indicating
significance at the 10%, 5%, 1% level.

I guess it is possible to do so by using outreg2 but it seems that I do
not
understand how to use this command correctly. 

Is there anyone who knows what to do ?
