sample condition
Posted: Mon Aug 06, 2012 8:00 am
I'm working with a forecasting horizon from 2012-2020 and a model that includes along other equation a text equation for a series X.
Forecasts for 2012 to 2013 (short-run) are "given" and implemented in the model by the model control command.
Hence, the text equation "only applies" to the period 2014-2020. Fine!
e.g.
Problem:
But how could I implement (ignoring the existing short-term forecasts) that for 2012-2013 an equation is used and from 2014-2020 the test equation? Manually there seems to be an option in properties ->endogenous-->secnarios excluded--> exclude sample. But this seems not to be the solution to the problem. Any suggestions to the code provided below???
