Hello, I have a quick question about haw gretl handles data imported from the BLS. If you download a series from the BLS, say into ms excel, you will get years with 5 quarters or 13 months. The Q5, or M13 for monthly data, is some annual summary of the data. What is the expected behavior of gretl in the case that I import the data without properly removing the non-observations, i.e. Q5/M13, from the csv file before importing? When I try this experiment in the import output I find "2001q05": BLS-type nonsense? Trying again Does gretl drop these rows from the data set? That is what appears to be happening. Also, is it terribly bad form to let gretl handle this issue rather than removing the rows before import?
