-cipolate- and -csipolate- (SSC) are user-written commands. Please remember that you are asked to explain where user-written commands you refer to come from. That said, all the hard work here in -csipolate- is done by official Mata functions. I don't see any obvious reason why this shouldn't work. You could try sending me the data privately to check, but I am going off-line now and will not be accessible for some hours.

None of my cities have observations for 1997, they all have observations on the variable in question for 1992 thru 2002.
