Estimating ordered categorical variables using panel data: a generalized ordered probit model with an autofit procedure
Pfarr, Christian; Schmid, Andreas; Schneider, Udo - Volkswirtschaftliche Fakultät, … - 2010
Estimation procedures for ordered categories usually assume that the estimated coefficients of independent variables do not vary between the categories (parallel-lines assumption). This view neglects possible heterogeneous effects of some explaining factors. This paper describes the use of an...

What happens if in the principal component analysis the Pearsonian is replaced by the Brownian coefficient of correlation?
Mishra, Sudhanshu K - Volkswirtschaftliche Fakultät, … - 2014
The Brownian correlation has been recently introduced by Székely et al. (2007; 2009), which has an attractive property that when it is zero, it guarantees independence. This paper investigates into the effects and advantages, if any, of replacement of the Pearsonian coefficient of correlation (r)...

Contrôle des systèmes de modélisation : un exemple de codage et de traçabilité des données
Buda, Rodolphe - Volkswirtschaftliche Fakultät, … - 2008
One can compare Econometrics with an Art which tries to minimize the lag between a quantitative law and a sample of data. Hence, the econometrics teaches us that before to built models, we must built data bank through strict procedures to prevent errors. Our paper presents classical methods to...
