Store a date and use in multiple sample
Posted: Wed Sep 19, 2018 8:01 am
Hi all,
I'm writing a programme in EViews for forecasting purpose. As it is made to be re-used at each forecasting exercise, I'd like to define the starting date (e.g. as of now "2018q3") in the beginning of the programme and then use it through the programme to define estimation samples. I don't know if this introduction is very clear. Maybe the code I wrote would be more informative:
The above code runs well, but it has to be ran all at once (otherwise, EViews loses the %prev_start from its memory). This is not very convenient as I have to run aaaaaaall my code when updating a single equation.
Is there a way to make the date more permanent in EViews' memory? I tried by doing:
But it does not run...
Is there any possibility to make this date more sticky into the memory ?
Thanks, all the best

%prev_start = "2018q3"
[...]
delete(noerr) s_xtr
sample s_xtr @first %prev_start-1 'Using the date to define estimation sample (and I have multiple estimation samples to do)
smpl s_xtr
equation xtr_ct.ls ... bla bla ...
[...]
delete(noerr) s_ulc
sample s_ulc "2004q1" %prev_start-1 'See: re-using it now for another estimation sample
smpl s_ulc
equation ulc_ct.ls ... bla bla ...
Is there a way to make the date more permanent in EViews' memory? I tried by doing:
Code: Select all
string prev_start "2018q3"
sample s_xxx @first prev_start
Is there any possibility to make this date more sticky into the memory ?
