Out-of-sample predictions with boosting model
...in the end I have an object bycountry that contains the in-sample
predictions of the model, estimated for each country separately. What I

Denmark, etc.
So I guess my problem is twofold. 1) How to make these out-of-sample
predictions, by country, when my data has not been declared as time-series?
