VARpred does not return pred when output=FALSE #3

Open lcallot opened 5 years ago

lcallot commented 5 years ago

The forecast is assigned to pred within the if (output) {...} statement, so that pred=NULL is returned when the argument output=FALSE is set in the call. The assignment of pred should probably be moved outside if (output){...}.
