In the context of binary classification with continuous predictors, we proove two properties concerning the connections between Partial Least Squares (PLS) dimension reduction and between-group PCA, and between linear discriminant analysis and between-group PCA. Such methods are of great...

The aim of this paper is to inquire into the possible relation between the FTAA (Free Trade Area of Americas) and the progressive interna- tionalization of the Euro. We will sustain that the actual productive situation (globalization) makes impossible to think of an FTAA with- out a kind of...

Nowadays the Government of industrialized countries, in presence of reduced public resources, has to assign clear objectives to public research laboratories to increase the competitiveness of firms. The purpose of this paper is to analyze the public research bodies of the National Research...

We analyze the implied volatility surface structure of ODAX options as traded on DTB (currently Eurex). We apply PCA to cross sections of the implied volatility surface taken along the same moneyness (m) or the same time to maturity (T). For data from the period October 3rd 1997 – November...

For many least-squares decomposition models efficient algorithms are well known. A more difficult problem arises in decomposition models where each residual is weighted by a nonnegative value. A special case is principal components analysis with missing data. Kiers (1997) discusses an algorithm...
