In the study of heart failure by Gwadry-Sridhar, et al. (2003), we have a situation in which, on the basis of a questionnaire, a score is obtained for each patient in either a Control or Treatment group at three different times. Thus for each patient in each group, we have a three dimensional vector of scores. These scores do not appear to be normally distributed and in addition many of the data vectors are incomplete. In this thesis, we propose a nonparametric approach for testing the agreement between control and treatment groups with missing values. We also demonstrate our approach by using the data from a study of heart failure.
