[R] estimates store -- Store and restore estimation results
estimates store name [, nocopy]
estimates restore name
estimates dir [namelist]
estimates drop namelist
where namelist is a name, a list of names, _all, or *.
_all and * mean the same thing.

estimates store name saves the current (active) estimation results under
the name name.
estimates restore name loads the results stored under name into the
current (active) estimation results.
estimates query tells you whether the current (active) estimates have
been stored and, if so, the name.
estimates dir displays a list of the stored estimates.
estimates drop namelist drops the specified stored estimation results.
estimates clear drops all stored estimation results.
estimates clear, estimates drop _all, and estimates drop * do the same
thing. estimates drop and estimates clear do not eliminate the current
(active) estimation results.
nocopy, used with estimates store, specifies that the current (active)
estimation results are to be moved into name rather than copied.
. estimates store hold, nocopy
is the same as typing
. estimates store hold
. ereturn clear
except that the former is faster. The nocopy option is sometimes
used by programmers.
. sysuse auto
. regress mpg weight displ
. estimates store myreg
. ... you do other things, including fitting other models ...
Restore regression results
. estimates restore myreg
For comparison, the same output is shown again
List stored estimates
. estimates dir
Drop estimates stored as myreg
. estimates drop myreg
After estimates restore myreg, things are once again just as they were,
estimationwise, just after you typed regress mpg weight displ.
estimates store stores results in memory. When you exit Stata, those
stored results vanish. If you wish to make a permanent copy of your
estimation results, see [R] estimates save.
The purpose of making copies in memory is (1) so that you can quickly
switch between them and (2) so that you make tables comparing estimation
results. Concerning the latter, see [R] estimates table and [R]
estimates dir stores the following in r():
r(names) names of stored results
