In order to pass from a population to a new individual by inference, de Finetti's idea of exchangeability is useful. This is shown in a simple logit model and in a multilevel model, with a larger number of observed groups, where the Simpson's paradox arises depending on whether you work on aggregate data or on group data. The concept of exchangeability permits, by using the appropriate probabilities, to solve a number of problems arising in statistical inference. But it is necessary to use not only the data but also information inferred by other means in order to make the final inference. Number 179, Fall 2007 Language   French Read the article Title Structural models and complexity of reality Author PELLOIS Christian Keywords Causality, Degree of difficulty, Differences, Implicative statistical analysis, Methodology, Precedence Topics Mathematical Statistics, Methodology, Modelling, Statistics Abstract Implicative statistical analysis expands the field of methods for processing the relationships between variables. In this sense, it represents an important advance in the realm of structural models applied to data. However, as with all processing models, its application in the social sciences poses difficult questions concerning the interpretation of results. Drawing upon the results of both previous and ongoing research, this article aims to evaluate the methodological difficulties of this model. Number 177, Spring 2007 Language   French Read the article Title How Ronald Fisher became a mathematical statistician Author STIGLER Stephen M. Keywords Fiducial inference, Maximum likelihood, Parameter, Sufficiency Topics History of Mathematics, History of sciences, Mathematical Statistics, Statistics Abstract In hommage to Bernard Bru, the story is told of the crucial influence Karl Pearson had on Ronald Fisher through a timely and perceptive editorial reply to a hasty and insufficiently considered short submission by Fisher.

We can already find in these writings a combination of several approaches and interpretations, ressembling that of the current practice which is a hybrid of Bayes-Laplace's, Fisher's and Neyman's conceptions of statistical testing.

Tribute issue to Bernard Bru Language   French Read the article Title The use of significance tests by psychologists, from normative, descriptive and prescriptive viewpoints Author POITEVINEAU Jacques Keywords Bayesian methods, Confidence intervals, Inductive reasoning, Methodology, Significance test, Statistical inference Topics Mathematical Statistics, Methodology, Probabilities, Psychology, Statistics Abstract At a normative level, the significance tests appear to be ill-suited and the main criticisms are reported. At a descriptive level, both examination of statistical textbooks, re-analyses of published papers and experiments about the use of significance tests by psychologists clearly reveals many misuses. At a prescriptive level, alternative solutions are considered, especially the Bayesian methods which appear to be especially attractive. Number 167, Fall 2004 Language   French Read the article Title Probability, demography and social sciences Author COURGEAU Daniel Keywords Demography, Epistemological probability, Frequence-type probability, Social sciences, Statistical inference Topics Demography, Epistemology, Mathematical Statistics, Modelling, Probabilities, Social Sciences Abstract This paper considers the different approaches to probability, that has been developed from the XVIIth century, compared to the simultaneous development of social sciences. If the frequency-type approach, for which the probability is the mathematical limit to which the relative frequency of an outcome converges, the epistemological approach, for which the probability concerns the available evidence it is reasonable to have a degree of belief in the truth of a given proposition, seems to be more suitable for social sciences. A presentation and a discussion of these two approaches are made here, with numerous examples of application to social sciences.

We begin by recalling the Lhoste's career from Artillery to Standardization. Number 162, Summer 2003 Language   French Read the article Title On money, file and death: the social investigations of Louis-René Villermé on differences in mortality according to income (1822-1830) Author LECUYER Bernard-Pierre, BRIAN Eric Keywords Ease, Longevity, Mortality, Political arithmetic, Statistics Topics Demography, Historical demography - History of Demography, History of sciences, Mathematical Statistics, Sociology, Statistics Abstract Louis-René Villermé, by his computations in political economy performed under the aegis of the Royal Academy of Medicine, based on administrative data, overthrows a timeless and fundamental topos of universal culture (money is powerless against death). Villermé establishes instead the existence of a direct relationship between ease (hence money) and longevity, and, naturally, of an inverse relationship between this same ease and mortality. A deep cultural revolution is at stake here concerning the perception of the relationships between money, life and death. The paper raises afterwards the question of the reasons why these daring results of political arithmetic of the years 1825 have only been accepted with a certain reticence by the official depositaries of the strictly statistical tradition of the Académie Royale des Sciences, i.e. the jury for the prize of statistics Auget de Montyon, and principally its referee Coquebert de Montbret.
