I see..
Thank you very much.

Thanks for reply :)

Already, I calculated various lags of var and I put the above 0 lags code as the sample to explain my circumstances.
On lags 1 or 2 or 3..., there are same problems, near singular matrix..
Thanks.

When I try following rolling regression, eviews 8 gives me "Near singular matrix in "VAR VAR1A!IA!Y.LS(NOCONST) 0 0 DRM4 @ RMM4*P4A1 RMM4*M4A1" :( for !i=1 to 413 smpl @first+!i-1 @first+98+!i '産出価格と投入価格のOLS equation b!i.ls value c soy '残差の変数作成 b!i.makeresid rm!i delete b!i Series rmm...

Ok! Thanks

Thanks for your reply!! In my Eviews 8, your code is working well! However, I tried following command with your code, It keeps giving me "Syntax Error in control statement in "For %n1a1 iid1a1"" :cry: .. create u 513 for !i=1 to 413 smpl @first+!i-1 @first+98+!i series meal=nrnd ...

Thanks for your early reply!!

However, I would like to put the value of scalar in equation name and select the equation from a lot of options, var0a1a1 to var0a1a100.

For example, in your code,
If scalar iid0a1's value is 53, then I want determine sc0a2=var0a1a53.@sc

Hi. I am beginner of programming of eviews :P I have formed a rolling regression analysis. And then, I want to put the scalar value in equation name as follows. putting the value of scalar iid0a1 in var0a1a{iid0a1's value}. I tried as following by programming, but it hasn't warked.. scalar iid0a1=@i...
