A new projection-based definition of quantiles in a multivariate setting is proposed. This approach extends in a natural way to infinite-dimensional Hilbert spaces. The directional quantiles we define are shown to satisfy desirable properties of equivariance and, from an interpretation point of...

Sustainable development assumes improvement in the quality of living of present and future generations by achieving social, economic and environmental balance. Demographic changes play a significant role in this process due to their long-term impact on social and economic outcomes. The...

Gower and Krzanowski (1999) described the analysis of a multivariate dataset that violated the assumptions of normality for multivariate analysis of variance. They developed a method comprising two aspects: a graphical representation of the points in a fewer number of dimensions, known as...

The aim of this paper is to give an overview of three important techniques; factor, cluster and discriminant analysis. I find it necessary and more important to have an understanding of the basic assumptions and the underlying foundations of the methods rather than a thorough mathematical...

The methods of analysis of acquired information from marketing researches must respond to the market environment. One of these methods which may be used is Conjoint Analysis. Conjoint Analysis allows: to denote how big the total efficiency of product (service) of particular quality represents...
