WebConsider a logistic regression model with a binary outcome variable named y and two predictors x 1 and x 2, as shown below. Logit(y)=β 0 +β 1x 1 +β 2x 2 + (1) The predicted values from (1), Logit(y), could be graphed as a function of x 1 and x 2 forming the logistic regression plane. Because this is a linear model, the plane is WebA first-order model with one binary predictor and one quantitative predictor that helps us answer the question is: y i = ( β 0 + β 1 x i 1 + β 2 x i 2) + ϵ i. where: y i is the birth weight of baby i. x i 1 is the length of gestation of baby i. x i 2 is a binary variable coded as a 1 if the baby's mother smoked during pregnancy and 0 if she ...
