Transition and measurement equation

Dear Michel,
I am trying to build a state transition and measurement equation from the decision rules that DYNARE produces. I saw that the transition equation can be build giving the command kalman_transition_matrix(dr_)after stoch_simul. But what about the measurement equation?
Many thanks!

Dear Rossana,

the measurement equation is trivial:

y^_t = Zyhat_t + ybar^* + trend + measurement error

y^t are the observed variables
ybar_t are the difference to the steady state obtained from the transition equation
Z is a selection matrix (which variables are observed)
is the steady state for the observed variables
trend is the deterministic trend for the observed variables
