Dear all:
When I choose the options of Model/Time series/ARIMA/Using X-12-ARIMA to gain a model,
are the explanatory variables such as as number of working days,day of week effects,
length of month etc included automatically already in the model ?
Is the model I get a RegARIMA model?
If it is not, how do I input the variables above in gretl 1.9.1 cvs ?
From where I can choose these variables and show their output in
gretl 1.9.1 cvs ?
Thanhs a lot
