Yes, there is a way around this, because you can use -parmest-. Stata 10 sers can still download the Stata 10 version of -parmest- from my website by typing, in Stata,

net from http://www.imperial.ac.uk/nhli/r.newson/stata10/

and the viewer will display a list of my Stata 10 programs, including the Stata 10 -parmest-.

And users of Stata Versions 9, 8, 7, 6 and 5 can similarly download compatible versions of -parmest- from my website by accessing the appropriate subfolder. For instance,

net from http://www.imperial.ac.uk/nhli/r.newson/stata9/

will give a list of my Stata 9 packages.

I hope this helps.

Best wishes

Roger

Hi Eric,

Thanks for your reply. The thing is I cannot use -parmest- because I am using
version 10.0 and Stata says it  can't run version 11.0 programs.

Is there a way around this? Please?

Dani

-parmest- from SSC is useful for this purpose.  Martin Weiss pointed  this out
to me in a post earlier this week.  E.g.,

****
webuse auto, clear
  regress price mpg weight foreign displacement headroom, nocons
  parmest,label  list(parm label t,clean noobs) saving(tstats, replace)

  u tstats, clear
keep parm t

Subject: Extracting the t-statistics from a regression output

Hi,

After I -regress y x1 x2 x3, noconstant- I need to access the vector of
t-statistics for the null that beta_i=0. This corresponds to the third column on

the regression output. I actually only need one of the t-stats but I don't think

this simplifies the problem.

 From the help article, I know that e(b) extracts the coefficients but couldn't
find something similar for the t-stats.

Any help would be appreciated.

Thanks,
Dani
