I am researching Dynamic Simultaneous Equation Models (DSEMs), and I understand that Gretl can handle this. I am certain of how endogenous variables respond to exogenous variables; however, I have encountered difficulty in algebraically demonstrating how endogenous variables could respond to each other within the model, as I found in Oxmetrics. I would be very grateful if you could assist me with materials that explain the algebraic representation of the mechanics involved.

Yours
