Ce livre étudie sous un angle first le thought de série temporelle, dont la complexité théorique et l'utilisation sont souvent resources de hardés. La théorie distingue par exemple les notions de séries stationnaire et non stationnaire, mais il n'est pas rare de pouvoir modéliser une série par deux modèles incompatibles. De as well as, un peu d'intimité avec les séries montre qu'on peut s'appuyer sur des graphiques variés pour en comprendre assez rapidement la construction, avant toute modélisation. Ainsi, au lieu d'étudier des méthodes de modélisation, puis de les illustrer, l'auteur prend ici le parti de s'intéresser à un nombre limité de séries afin de trouver ce qu'on peut dire de chacune.

Smoothing solutions have been little employed inside the social sciences. Semiparametric Regression for that Social Sciences sets out to deal with this situation by offering an available introduction to the redirected here subject, stuffed with examples drawn with the social and political sciences.
