Some Simple Rules for Interpreting Outputs of Principal Components and Correspondence Analysis
نویسنده
چکیده
A large literature has been devoted to the assessment of the right number of eigenvalues in PCA and CA (two-way and multiple). Most of the publications are based on distributional assuptions for the sample, or on bootstrap techniques. After having recalled some of the most important results, we present simple thresholds based on a « control chart » approach for eigenvalues as well as for contributions, distances...

Perceptual maps: the good, the bad and the ugly
Perceptual maps are often used in marketing to visually study relations between two or more attributes. However, in many perceptual maps published in the recent literature it remains unclear what is being shown and how the relations between the points in the map can be interpreted or even what a point represents. The term perceptual map refers to plots obtained by a series of different techniqu...
متن کاملFunctional Analysis of Iranian Temperature and Precipitation by Using Functional Principal Components Analysis
Extended Abstract. When data are in the form of continuous functions, they may challenge classical methods of data analysis based on arguments in finite dimensional spaces, and therefore need theoretical justification. Infinite dimensionality of spaces that data belong to, leads to major statistical methodologies and new insights for analyzing them, which is called functional data analysis (FDA...
متن کاملA new approach based on data envelopment analysis with double frontiers for ranking the discovered rules from data mining
Data envelopment analysis (DEA) is a relatively new data oriented approach to evaluate performance of a set of peer entities called decision-making units (DMUs) that convert multiple inputs into multiple outputs. Within a relative limited period, DEA has been converted into a strong quantitative and analytical tool to measure and evaluate performance. In an article written by Toloo et al. (2009...
متن کاملTen Simple Rules for Designing and Interpreting ERP Experiments
Overview This chapter discusses some of the central issues in the design and interpretation of ERP experiments. Many design and interpretation issues are unique to a given content area, but many principles apply to virtually all ERP studies and these common principles are the focus of this chapter. The chapter begins with a discussion of the nature of ERP components, an issue that lies at the h...
متن کاملتجزیه و تحلیل مولفه های اصلی صفات کیفیت داخلی تخم مرغ و برخی از صفات عملکردی مرغ‌های بومی آذربایجان
One of the main problems of multiple-trait genetic evaluation in poultry breeding is high computing costs. Principal components analysis (PCA) is a method for reducing the number of traits in correlated trait analysis. The aim of the present study was to determine the most effective principal components (PCs) of internal egg quality and some performance traits of Azarbayjan native chickens. ...
