...Factor Analysis in SPSS To conduct a Factor Analysis, start from the “Analyze” menu. This procedure is intended to reduce the complexity in a set of data, so we choose “Data Reduction” from the menu. And the choice in this category is “Factor,” for factor analysis. This dataset gives children’s scores on subtests of the Wechsler Intelligence Scale for Children (WISC-III). The Wechsler scales are scored to give you a “verbal” and a “performance” IQ. The question is whether we can reproduce the verbal vs. nonverbal distinction, with the appropriate subtests grouping into each category, using factor analysis. This dialog box will appear: Factor analysis has no IVs and DVs, so everything you want to get factors for just goes into the list labeled “variables.” In this case, it’s all the variables. In some datasets, there is also a dummy “subject number” variable included. Be sure that you don’t include subject number as one of the variables for your factor analysis! To do a factor analysis, we need to select an “extraction method” and a “rotation method.” Hit the “Extraction” button to specify your extraction method. In this dialog box, you can make a number of selections. First, I want you to un-check the box labeled “Unrotated factor solution.” This is a default setting for your printout, but it just gives you information that you don’t need, and that may distract you from the real answers. So, always go into the Extraction sub-dialog and un-check this...

...Chapter 14 Factor analysis 14.1 INTRODUCTION Factor analysis is a method for investigating whether a number of variables of interest Y1 , Y2 , : : :, Yl, are linearly related to a smaller number of unobservable factors F1, F2, : : :, Fk . The fact that the factors are not observable disquali¯es regression and other methods previously examined. We shall see, however, that under certain conditions the hypothesized factor model has certain implications, and these implications in turn can be tested against the observations. Exactly what these conditions and implications are, and how the model can be tested, must be explained with some care. 14.2 AN EXAMPLE Factor analysis is best explained in the context of a simple example. Students entering a certain MBA program must take three required courses in ¯nance, marketing and business policy. Let Y1, Y2 , and Y3 , respectively, represent a student's grades in these courses. The available data consist of the grades of ¯ve students (in a 10-point numerical scale above the passing mark), as shown in Table 14.1. Table 14.1 Student grades Student no. 1 2 3 4 5 Finance, Y1 3 7 10 3 10 Grade in: Marketing, Y2 6 3 9 9 6 Policy, Y3 5 3 8 7 5 °Peter Tryfos, 1997. This version printed: 14-3-2001. c 2 Chapter 14: Factor analysis It has been suggested that these grades are functions of two underlying factors, F1 and F2, tentatively and rather loosely described as quantitative ability and verbal ability, respectively. It is...

...Step 3: Conducting an Exploratory Factor Analysis Exploratory Factor Analysis (EFA) is a technique to find the latent variable(s) that is being manifested by a set of observable variables. In our research, EFA was used with the objective to find if our latent variable had multiple dimensions or not (Williams, Onsman, & Brown, 2010). An important assumption of EFA is that observed variables should be multivariate normal 14. However this assumption was violated for our data. If multivariate normality assumption is violated then it is recommended to use the “Principal axis factors” method which is also known as “Principal Factor” as appose to the Maximum Likelihood factor analysis method (Fabrigar, Wegener, MacCallum, & Strahan, 1999). The difference between these two methods lies in the differences between the discrepancy function that they minimize (See Appendix)....

...Human Factors Analysis and Classification System Abstract As aircrafts become more reliable over the years, humans have progressively become more of a causal factor in aviation accidents. Thus, being able to analyze an accident from a human factor perspective is of paramount importance. However, a proper framework of accident analysis is necessary to address the complex and often nebulous nature of human error. The Human Factors Analysis and Classification System Maintenance Extension (HFACS-ME) is one such framework that serves as an accident investigation and data analysis tool. This article will analyze how HFACS-ME is used from an applied perspective and demonstrate its utility using case studies. Human Factors Analysis and Classification System Maintenance Extension The Human Factors Analysis & Classification System (HFACS) was originally developed to analyze and classify human errors and other factors contributing to aviation incidents. HFACS combines features from Heinrich’s “Domino Theory” and Edward’s “SHEL Model” as well as Reason’s model to uncover factors that contribute to accidents (Schmidt, J. Lawson, D., n.d.). The Maintenance Extension of HFACS termed HFACE-ME was created to address aviation maintenance related incidents and facilitates the recognition of defective or absent defenses at four levels namely, Unsafe: Management Conditions, Maintainer Conditions, Working Conditions, and Maintainer...

...Factor Analysis Assignment 1. The principal component analysis is the approach that is used for data reduction and creation of one or more than one index variables from the large number of variables. This happens with the use of linear combination of variables. The index variable that is created from this analysis is called components. While, the Factor Analysis is the approach that is used for data reduction in different way than principal component analysis. It is the measurement model of latent variable. This cannot be measured directly with one variable rather, it is observed through the relationship between x and y variables. 2. The general approach (Kaiser) is to retain factors with eigenvalue ≥ 1 and eliminate factors with eigenvalue...

...INTERNATIONAL FACTORS OF ENVIRONMENT Public administration operates in a global environment that requires a greater emphasis on cooperation among nations. Globalization has become a catch world for international development endeavors throughout the world. With globalization borders between regions and nations are no longer important. A final component of the general environment is actions of other countries or groups of countries that affect the organization. Governments may act to reserve a portion of their industries for domestic firms, or may subsidize particular types of businesses to make them more competitive in the international market. Some countries may have a culture or undergo a change in leadership that limits the ability of firms to participate in the country's economy. As with the other elements of the macroenvironment, such actions are not directed at any single company, but at many firms. ECONOMIC ASSOCIATIONS. One of the most recent joint efforts by governments to influence business practices was NAFTA. The agreement between the United States, Canada, and Mexico was intended to facilitate free trade between the three countries. The result has been a decrease in trade barriers between them, making it easier to transport resources and outputs across national boundaries. The move has been beneficial to many businesses, and probably to the economies of all three countries. In most economic associations, preference is also given to products from member countries...

Ringle, University of Hamburg & University of Technology, Sydney, cringle@econ.uni-hamburg.de Siegfried Gudergan, University of Technology Sydney, Siggi.Gudergan@uts.edu.au Abstract Fan satisfaction is with services is a key element to successfully compete in the soccer industry. In this paper we examine the antecedent factors that explain the variations in overall service satisfaction judgements. We draw on service an activities put in place by soccer clubs to illustrate these effects. Based on a literature review, interviews with both soccer fans and an industry expert, we develop a measurement approach for satisfaction which we test subsequently using a large-scale sample among soccer fans. An analysis of the impact-performance implications of antecedent drivers shows that stadium features, team characteristics, and fan-based support for the club and its management are the most important factors that influence overall satisfaction.

...science and GSR (Galvanic Skin Response) data. As a result of this study, the authors suggest two models of movie trailers boosting customers’ appreciation desire to make a new movie trailer. Keywords: Movie Trailer Production Approach Model; Statistics; GSR INTRODUCTION O ver the last several years, the authors have been conducting applied research on a Customer Science Approach. In this study, the authors research “Effectiveness of Movie Trailers Boosting Customers’ Appreciation Desire” using statistical science and GSR (Galvanic Skin Response) data. First, shared factors that form the backdrop for the structural elements of movie trailers are identified (picture, story, function, etc.) and a numerical model is used to assess their relative impact. Next, GSR experiments are used as a new way to visualize viewers’ emotional responses and identify key factors that motivate them to see the advertised film. Key factors that affect viewer emotions (including changes in picture brightness, changes in the soundtrack, and sound effects) are then traced via changes in the physical chemistry of the test subjects. The authors then use the information gathered during these tests to formulate two new systematic models for creating movie trailers that will effectively motivate viewers to see the advertised film. The models are applied to the remaking...
