Subject | RE: st: saving residuals for many regressions |

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. Geoff.

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 -------------------------- Maarten L.
