Purpose. . of Electronic and Information Engineering, The Hong Kong Polytechnic University enmwmak@polyu.edu.hk Abstract This document provides the detailed formulations of factor analysis (FA) models in which the observed vectors are assumed to follow a mixture of Goals for Lecture Notes #3 •Introduce contrasts •Introduce post hoc tests •Review assumptions and issues of power 1.Planned contrasts (a)Contrasts are the building blocks of most statistical tests: ANOVA, regression, MANOVA, discriminant analysis, factor analysis, etc. Next, each factor is provided a weight between '0'to '1'according to the level of importance, where '0'denotes least important and '1'denotes most important. 3. . ! Factor analysis Assume that we have a data set with many variables and that it is reasonable to believe that all these, to some extent, depend on a few underlying but unobservable factors. A Simple Explanation… Factor analysis is a statistical procedure used to identify a small number of factors that can be used to represent relationships among sets of interrelated variables. Factor Analysis (23 and 25 September). Factor Models • Suppose there are k assets (most often stocks), and T periods. .
