Dear Jack and Sven,

I am trying to estimate an SVECM subject to long run restrictions using the SVAR package (version 1.34, Gretl 2018a, Win 10). I found out that although cointegration case 3 (unrestricted constant) works well, case 4 (trend restricted to the cointegration space) produces the following error message:

Matrices not conformable for operation

*** error in function vecm_est, line 87
> matrix mu = olspar[1,] | (jalpha * jbeta[n+1,])'
called by function SVAR_estimate

Error executing script: halting
> SVAR_estimate(&sv)

I restrict all the coefficients in beta beforehand. I also restrict those in alpha, but I don't think this is relevant.

Could you take a look on it?

Thank you in advance,

Andreas Zervas

P.S. Is it possible to change the pink color in IRFs graphs from the SVAR package?
