There's nothing special about dummy variables as far as EViews is concerned, so the fact that it is a dummy is irrelevant. The most likely cause of this is that the Excel file has lots of missings at the start (i.e. the first X rows), which means that EViews cannot automatically detect the type of data in that column properly. Without seeing the Excel file, it is hard to comment further.
You can convert from the non-numeric series to a numeric series using the @val function:
- Code: Select all
series mydummy = @val(dummy)
where dummy is the alpha series (the one with the "abc" logo).
