Dear all,

we have been entering lung function data over the course of the last
few month. To be able to identify mistyped data we have entered all
data twice. So for a patient who received a lung function measurement
on 12 Jan 2002 I have two observation holding all the data gained from
that measurement.

I am now wondering wether there is an easy way to compare those two
observations? The data could look like this

patid	lufudate	fvc	fev1
1	10jan2002	5.1	4.8
1	10jan2002	5.1	4.3
2	09jan2002	4.3	3.7
2	09jan2002	4.3	3.7
3	08jan2002	2.9	2.6
3	08jan2002	2.9	6.2

(This is articial data that I just made up. The "real" data contains
approx. 20 parameters)

So is there any program out there that would help me with this task?
Thank you for your suggestions!

Kind regards,
sebastian
