update: As Ksharp suggested, I reposted this question in the forecasting forum:
Hi all,
I am trying to run a pooled regression for a sample. here is the code that I have right now:
data have;
input fundid time flow flow_lag return;
datalines;
10001 1 10 . .01
10001 2 12 10 -.03
10001 3 -10 12 .04
10002 1 61 . .03
10002 2 36 61 .04
10002 3 10 36 0.01
;
run;
proc panel data = have;
id fundid time;
model flow = return flow_lag / pooled;
run;
Of course, I have lots of funds and lots of time periods. But I am just showing 2 funds and 3 time periods to understand better how the proc panel works.
When I run the above regression, I get the error:
There is only one cross section or time series observation. Computations will be terminated.
I get this message even when I run on the whole sample, which I know has lots of cross section and time series. As far as I understand, I have both multiple cross sections (two fundids) and multiple time series (three time ids). So I think there should be something about pooled regression that I do not get at all.
Here are my two questions
If there is any reference that can help me, I would appreciate it if you mention it as well.
thanks a lot,
It is about SAS/ETS, plz post it at Forecast forum.
