Bland-Altman method with repeated measures

[kende jan]

Dear all,
 
I want to use the Bland-Altman method to measure agreement with repeated measures collected over period of time (seven periods).

How can I do this with SPSS

 
Many thanks
Jan

Have you taken a look at this paper?:

http://www-users.york.ac.uk/~mb55/meas/bland2007.pdf  ("AGREEMENT
BETWEEN METHODS OF MEASUREMENT WITH MULTIPLE OBSERVATIONS PER INDIVIDUAL")

Also, I have a macro for Bland&Altman LOA analysis with pairs of
measures (you can download it from http://gjyp.nl/marta/  ). Perhaps you
can modify it for repeated measures, the methodology is quite simple
from a computing point of view.
