Hi! Bruzzle!
Why in a file usmodel.mod in the measurment equations are present ctrend, but in a file of the data (usmodel_data) is no ctrend?
Sorry for my English. I’m from Russia.
Hi Leonid,
The data is detrended to make sure that the linearized model and the data are consistent. Then we are estimating the trend variables.
Hope this answers the question.

Hi Bruzzle!
Thank you for your reply on my question!
But I have a new question.
But then the variable dc =c-c(-1)+ctrend (for example) in the measurment equation does not correspond to a observed variable (varobs)dc=c-c(-1)?
