Re: Tracking and Evaluating Model Forecasts

Thank you, Gareth. In that case, shouldn't it be: 'define scenarios for %i M2 G RS %scenname = "Scenario " + %i mymodel.scenario(a=%i, n) %scenname ' move fcst_sample !step obs at a time for !j = 1 to 8 step !step ' set fcst_sample to forecast period smpl 2001q1 2001q1+!j ' solve model for...

Re: Tracking and Evaluating Model Forecasts

Thanks! But now I get the following error when I try to solve the model using 'define scenarios for %i M2 G RS ' move fcst_sample !step obs at a time for !j = 1 to 8 step !step ' set fcst_sample to forecast period smpl 2001q1 2001q1+!j ' solve model for alternative scenario %scenname = "Scenari...

Re: Tracking and Evaluating Model Forecasts

Yet further to this: If I try to run a modification of your code, as follows, for %i=1 M2 G RS %scenname = "Scenario " + {%i} mymodel.scenario(a=%i) %scenname next I get the error "String added to series in "%senname = "Scenario " + M2"." Obviously I have not ...

Re: Tracking and Evaluating Model Forecasts

Further to this:

Is it possible when using the "scenario" command in a loop to name the newly created scenario according to a wildcard, for example

mymodel.scenario(...) "Scenario {%0}"

where the {%0} is determined within the loop?

Thanks

Re: Tracking and Evaluating Model Forecasts

Thank you. I am looking at the "rollfcst" programmes and this Forum for guidance on how to do the programming, as I have no experience whatsoever with EViews

Hello, I am new to EViews and need help on the following Model problem: Having estimated a model, I need to create for each tracked endogenous variable over each of successive n-step forecasts, where n = 1, 2, ..., 8: 1) a table (in the form of a matrix filled with blocks of data, with "rows&qu...
