Hi Jack,

It is nice that the Blanchard-Quah model was given an example in the revised manual. However, as I try it I stumbled upon an error which I think, requires my matrix to be positive definite. The following is the script code shown:

Matrix is not positive definite

*** error in function imp2exp

> matrix s = R'invpd(R*R')*d

 called by function init_C

 called by function SVAR_estimate

Error executing script: halting

> SVAR_estimate(&Mod)

Any feedbacks about this?

Many thanks,

Deborah
