WebEn statistiques, en économétrie et en apprentissage automatique, un modèle de régression linéaire est un modèle de régression qui cherche à établir une relation linéaire entre une variable, dite expliquée, et une ou plusieurs variables, dites explicatives. On parle aussi de modèle linéaire ou de modèle de régression linéaire .

WebThe p-value is the probability of observing a t-statistic that large or larger in magnitude given the null hypothesis that the true coefficient value is zero. If the p-value is greater than 0.05--which occurs roughly when the t-statistic is less than 2 in absolute value--this means that the coefficient may be only "accidentally" significant. crystal and stone meaningsWeband Its Extension, Communications in Statistics - Theory and Methods.
