I've noticed the tsset is interchangeable, at times. Anyhow, I thought
tfill would fill in the dates between 11sep2009 and 15sep2009
(12sept2009, 13sep2009, and 14sep2009). I thought that is what the
help says, but maybe I read it wrong. How would I fill in those
missing dates? I need to do this to more easily merge another data set
(so I can generate an average of another variable, over the time
period).
