Hello

I have a panel dataset and I want to run a loop to sequentially increase the time dimension of the sample like:

for !i = 1 to 12
smpl @first 2012M12+!i
...estimate equation
next

I am bit confused but it looks like this does not increase the time dimension of the sample. Is that right? And is there an efficient way to address this?

Thanks
George

That's exactly what it does.

Code: Select all


wfcreate m 2010 2015 10
series y=nrnd
series x=nrnd


table samples
for !i = 1 to 12
	smpl @first 2012M12+!i
	equation eq!i.ls y c x
	samples(!i,2) = eq!i.@smpl
	samples(!i,1) = !i
next

show samples
