RE: st: saving residuals for many regressions

["G Livesey" <glivesey@inlogic.co.uk>]

Maarten, Rodrigo

I looked at this and got the same answer, all resids having periods-- but
only when the program did not run through fully.

Rodrigo, 

I suggest ensuring Maarten's example is copied fully-- and executed fully.
If you have to edit, try to start afresh, but ensure graphs are not saved
when starting afresh --use for example, command: graph drop _all.

When the programme runs though fully then 'resid' includes  residuals for
each level in a single column. If you wanted them in separate columns then
include:

predict resid_`lev' if e(sample),resid 

immediately after the command to predict resid_t, but this is not a very
efficient way to store the information.

Hope this helps.

Not true, look again at the code I gave you, in particular
the various -if- conditions. What is droped is resid_t, 
while the variable resid contains the residuals for each
of the estimation samples. So the values in resid for
those observations with rep78 == 2, are from the regression
in rep78 == 2, while the values in resid for the observations with rep78 ==
3 refer to the regression on the sub-sample where rep78 == 3, etc. 

Hope this helps,
Maarten
