### Re: Forming a series

"Inverse standard deviation" weighting (probably with "none" scaling, though that depends on what you view the purpose of weighting). hi glenn, just to confirm w*y=w*x+w*c where weight=w is as u mentioned above? can i know what is the scaling abt and how do i program it? eq.ls(w...

### Re: Forming a series

The second argument in the @wlookup function indicates what type of object to look for. You have it set to "series", when you're looking for scalars. hi gareth, my apology it doesnt work even if one sets it to scalar (it was a poor cut and paste). can i by any chance call them so that i c...

Dear Gareth, i have attached anew workfile. can i ask how could i code something so that it compares k_baa1 with k_daa1 with k_faa1 with k_haa1 with k_jaa1 (all scalars) and find the smallest one given that i would like 1,2,3...42 instead. i tried @wlookup with this code to call and then verbally in...

hi Gareth, 1. gd knowing var lags can be looped. :) 2. the one with f_sti and d(f_sti) still does not work as i was hoping to get eq1: ls. y x c eq2: ls. d(y) x c etc. and then allow y to change in variable thats why i asked about %deplist = @wlookup("a*", "series") with the idea...

### Re: Impulse response to Cholesky 1% shock

Create a user defined shock matrix: matrix(2,1) myimpulse myimpulse.fill(by=c) 0,1 And then type the name (i.e. myimpulse) in the edit box. As far as I understand, you are trying to estimate the impact of an oil price shock on the inflation. If that is your case, then I strongly recommend you to us...

hi Gareth,

thank you once again. that i know. just wondering is there a way i can get hold of VAR source code? c-lang?
or how can i finetune BVAR program code?
much much appreciated.
