Espace, populations, sociétés - Année 1985 - Volume 3 - Numéro 1 - Pages 240-247Theoretical bases and models for an investigation into the family, occupational and migratory biography. The study of relations between migrations and occupational and family biography are developed through two complementary ways. The non parametric analysis, generalizing the longitudinal analysis, allows us to isolate local dependencies and independencies between events providing a very wide network of analysis. The parametric analysis, generalizing the analysis of regression, allows to highlight very close links between various phenomena already studied. Finally, these methods are used in the study of more complicated cases. 8 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
