Erasmus University Rotterdam
Erasmus University Rotterdam ( ; abbreviated as EUR) is a public research university located in Rotterdam, Netherlands. The university is named after Desiderius Erasmus Roterodamus, a 15th-century Christian humanist and theologian.

Exploratory Factor Analysis
In multivariate statistics, exploratory factor analysis (EFA) is a statistical method used to uncover the underlying structure of a relatively large set of Variable (research), variables. EFA is a technique within factor analysis whose overarching goal is to identify the underlying relationships between measured variables. It is commonly used by researchers when developing a scale (a ''scale'' is a collection of questions used to measure a particular research topic) and serves to identify a set of Latent variable, latent constructs underlying a battery of measured variables. It should be used when the researcher has no ''a priori'' hypothesis about factors or patterns of measured variables. ''Measured variables'' are any one of several attributes of people that may be observed and measured. Examples of measured variables could be the physical height, weight, and pulse rate of a human being. Usually, researchers would have a large number of measured variables, which are assumed to b ...

Multidimensional Scaling
Multidimensional scaling (MDS) is a means of visualizing the level of similarity of individual cases of a data set. MDS is used to translate distances between each pair of n objects in a set into a configuration of n points mapped into an abstract Cartesian space. More technically, MDS refers to a set of related ordination techniques used in information visualization, in particular to display the information contained in a distance matrix. It is a form of non-linear dimensionality reduction. Given a distance matrix with the distances between each pair of objects in a set, and a chosen number of dimensions, ''N'', an MDS algorithm places each object into ''N''-dimensional space (a lower-dimensional representation) such that the between-object distances are preserved as well as possible. For ''N'' = 1, 2, and 3, the resulting points can be visualized on a scatter plot. Core theoretical contributions to MDS were made by James O. Ramsay of McGill University, who is also ...

Econometric Institute
Econometric Institute (Dutch ''Econometrisch Instituut'') at the Erasmus University Rotterdam is a leading research institute in the fields of econometrics and management science in the Netherlands. The Institute offers advanced education in econometrics. It was founded in 1956 by Henri Theil in cooperation with Jan Tinbergen. History Foundation The first proposal for a special institute in quantitative economics at the Netherlands School of Economics in Rotterdam was made by Henri Theil in 1953 with support of Jan Tinbergen, while working at the Central Planning Bureau. The senate of the school added the requirement that it "would not confine itself to economic applications, but would also give attention to business problems, which implied that operations research had to be included in the program."Pedro Garcia Duarte (2007) ''Constructing Concepts of Optimal Monetary Policy in the Postwar Period.'' p. 35 In the year 1955–56 Theil was Visiting Professor at the University o ...
