Dear users,
I have an unbalanced panel of students ("id" = 1, 2, ..., 5040), from 1998 to 2002 ("time"), and a number of variables (ex. body weight...). I need generate a complete panel dataset, by eliminating every student for which there is at least a single item data missing for a year (or more). Could you help me with an example? Thank you.
