Probabilistic discrete-choice models, such as multinomial logit models, are widely used to predict changes in market shares or total demand resulting from changes in policy variables under management control. These models often are evaluated in terms of their ability to predict choices in a...

L'estimation de la mobilite intergenerationnelle du revenu pose une foule de problemes de mesure, puisque le chercheur n'observe pas le revenu permanent, durant toute la vie. Les auteurs de presque toutes les etudes font une correction afin de tenir compte de la variation moyenne du revenu...

The estimation of intergenerational earnings mobility is rife with measurement problems since the research does not observe permanent, lifetime earnings. Nearly all studies make corrections for mean variation in earnings because of the age differences among respondents. Recent works employ...

We propose and test new adaptive question design and estimation algorithms for partial profile conjoint analysis. Polyhedral question design focuses questions to reduce a feasible set of parameters as rapidly as possible. Analytic center estimation uses a centrality criterion based on...

Contexte : Le poumon est depuis plusieurs annees le principal siege de cancer causant le deces pour les hommes et il est devenu depuis 1994 egalement laprincipale cause de deces par cancer pour les femmes au Canada. Il est donc important d'evaluer les ressources necessaires a son diagnostic et a...

Context : Lung cancer has been the leading cause of cancer deaths in Canadian males for many years, and since 1994, this has been the case for Canadian femalesas well. It is therefore important to evaluate the resources required for its diagnosis and treatment. This article presents an estimate...

This paper presents a definitive description of neural network methodology and provides an evaluation of its advantages and disadvantages relative to statistical procedures. The development of this rich class of models was inspired by the neural architecture of the human brain. These models...

Studies estimating the Bass model and other macro-level diffusion models with an unknown ceiling feature three curious empirical regularities: (i) the estimated ceiling is often close to the cumulative number of adopters in the last observation period, (ii) the estimated coefficient of social...

Introduction : Le contexte economique actuel oblige tous les partenaires des reseaux de soins de sante, qu'ils soient publics ou prives, a identifier les facteurs qui conditionnent l'utilisation des services de soins de sante. Pour ameliorer notre comprehension des phenomenes qui sous-tendent...

<strong>Introduction:</strong> In the current economic context, all partners in health care delivery systems, be they public or private, are obliged to identify the factors that influence the utilization of health care services. To improve our understanding of the phenomena that underlie these relationships,...
