Complexity And Simplicity As Objective Indices Descriptive Of Factor Solutions

Kaiser's simplicity index is compared and contrasted with Hofmann's complexity index and it is suggested that when used together they provide an objective basis for comparing different factor solutions for the same data set.

Abstract

Kaiser's simplicity index is compared and contrasted with Hofmann's complexity index. It is noted that at the variable level one index may be derived algebraically from the other; however, each provides different descriptive information with regard to a factor solution. Furthermore it is suggested that when used together they provide an objective basis for comparing different factor solutions for the same data set.
