Hi,
My apologies for omitting the source for the commands -csipolate- and -cipolate- (SSC) - those are user-written commands by Nicholas Cox.
Thank you for the offer to take a look at the data - I'm happy to send it, but it's probably not worth your trouble, as I was just looking to compare the cipolate results to the csipolate results.
Mike

-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.
