To the Gretl community, I am trying to do the long run Structural VAR using 9 variables. With the (n^2-n)/2 formula, I am left with 36 constraints. I used the C-model and I was able to restrict the template matrix but I cannot seem to generate the SVAR result. The following is the Hansl code shown: Index value 0 is out of bounds. *** error in function init_C, line 4 called by function SVAR_estimate called by function GUI_SVAR May I know what went wrong here? Your help is greatly appreciated.
