The Use of Set Theory and Cluster Analysis to Investigate the Constraint Problem in Factor Analysis in Dynamic Structures (FADS)

Chapter

Abstract

In recent years factor analysis has played an increasingly important role in the analysis of nuclear medicine dynamic studies. Schmidlin (1979) demonstrated how the technique could be applied to a time sequence of images where each pixel gives rise to a dynamic curve (sometimes called a dixel). The premise is made that each dixel may be approximated by a linear combination of a few components. These are chosen in such a way that, for a given number of components, the least squares error of the approximation to the population of dixels is a minimum.
