fonction linéaire. Graphiquement, la relation est représentée par une droite d'équation y = b0 +b1x. Ce modèle particulier comporte deux paramètres (coe cients) : le coe cient b1: la pente de la droite; b1 > 0 si la droite est croissante, b1 = 0 si la droite est

Chapitre 4 : Régression linéaire

Pour un âge x donné, la tension d'un individu est la somme de deux termes : - 1er terme : b0 + b1x entièrement déterminé par l'âge; - 2ème terme : le terme d'erreur ε qui ariev de façon aléatoire d'un individu à l'autre. Le terme d'erreur ε est une ariablev aléatoire. Elle synthétise toutes les ariablesv in uant sur la tension et qui ne sont pas prises en compte.

1. Linear Probability Model vs. Logit (or Probit)

Linear Probability Model Logit (probit looks similar) This is the main feature of a logit/probit that distinguishes it from the LPM – predicted probability of =1 is never below 0 or above 1, and the shape is always like the one on the right rather than a straight line.

Multinomial Logistic Regression

the ‘exp’ function applied to the coefficients. The Exp(B) is the odds ratio associated with each predictor. We expect predictors which increase the logit to display Exp(B) greater than 1.0, those predictors which do not have an effect on the logit will display an Exp(B) of 1.0 and predictors which decease the logit will have Exp(B)

This result is based on the rest of our
