Hello,
I am little bit confused about the notation of measurement equations and the inclusion of deterministic trends. Example: if the measurement variables for the consumption in my model is "c", and the deterministic component is a constant and linear
time trend
!dtrends
dataC += dataC_ +dataCt_ * !ttrend;
should I write as a measurement equations for the consumption "c" in deviation from its steadystate
!measurement_equations
'Observables  Consumption'
dataC = log(c/$c);
or in level
!measurement_equations
'Observables  Consumption'
dataC = log(c);
In the estimate function, I set "deviation" to false and "dtrends" to true.
Thanks,
Gabriel
