Degrees-of-freedom tests for smoothing splines
When using smoothing splines to estimate a function, the user faces the problem of choosing the smoothing parameter. Several techniques are available for selecting this parameter according to certain optimality criteria. Here, we take a different point of view and we propose a technique for choosing between two alternatives, for example allowing for two different levels of degrees of...

Welfare Rankings in the Presence of Contaminated Data
Stochastic dominance criteria are commonly used to draw welfare-theoretic inferences about comparisons of income distribution as well as ranking probability distributions in the analysis of choice under uncertainty. However, just as some measures of location and dispersion can be catastrophically sensitive to extreme values in the data it is also possible that conclusions drawn from...

High Breakdown Estimation of Multivariate Location and Scale With Missing Observations
In this paper, we consider the problem of outliers in incomplete multivariate data, when the aim is to estimate a measure of mean and covariance as it is the case for example in factor analysis. In such a situation the ER algorithm of Little and Smith (1987) which combines the EM algorithm for missing data and a robust estimation step based on an Mestimator could be used. However,...

Robust Inference with Binary Data
In this paper robustness properties of the maximum likelihood estimator (MLE) and several robust estimators for the logistic regression model when the responses are binary are analysed. It is found that the MLE and the classical Rao's score test can be misleading in the presence of model misspecification which in the context of logistic regression means either misclassification...

Robust Estimation and Inference for Generalised Latent Trait Models
The paper discusses the effect of model deviations such as data contamination on the maximum likelihood estimator (MLE) for a general class of latent trait models (citeNP{MoKn:00}). This is done with the use of the influence function (Hampel 1968, 1974) a mathematical tool to assess the robustness properties of any statistic, such as an estimator. Simulation studies show that the MLE...

Mécanismes de régulation de la structure des qualifications et spécificité du capital humain. Une analyse du capital social des conseillers bancaires
A partir d’une analyse du secteur bancaire, cet article établit que les mécanismes de régulation de l’emploi que sont la flexibilité interne et externe sont bien déterminés par la spécificité du capital humain, conformément aux théories dualistes du marché du travail. Il montre ensuite que cette spécificité est marquée par l’encastrement des conseillers bancaires dans les réseaux...

Ethique, droit et société : une approche des sciences sociales
Cette contribution examine deux théories issues des sciences sociales et du comportement et qui enrichissent le débat sur les relations entre éthique et droit. Il s'agit d'une part de la théorie des systèmes clos élaborée par le sociologue Niklas Luhmann et qui met en lumière la nécessaire "amoralité" du système du droit. L'autre théorie est celle du...
