Missing values may occur in blocks of two or more. Suppose you want to replace missings by the previous nonmissing value, whenever it occurred, so that given _n myvar 1 42 2 . 3 . 4 56 5 67 6 78 you want toreplacenot onlymyvar[2], but alsomyvar[3]with 42. ...
My data is only numeric, and the number of unique values of variablesxandyis large, so I am looking for a general rule that works in every case. I am thinking on using the user-written commandcarryforward, running something like bysort x: carryforward y if x != . , repl...
