1. Binomial logistic regression model 尽管线性分类器方法足够简单并且使用广泛,但是线性模型对于输出的 y 没有界限,y 可以取任意大或者任意小(负数)的值,对于某些问题来说不够 adequate, 比如我们想得到 0 到 1 之间的 probability 输出,这时候就要用到比 linear regression 更加强大的 logistic regression...

The Multiple Linear Regression Model Multiple linear regression, also known simply as multiple regression, is used to model quantitative outcomes. In multiple regression, the model may be written in any of the following ways: Y=β0+β1X1+β2X2+…+βpXp+ɛ ...
regression modelingThis chapter discusses methods for predictor variable selection by using two examples. The first example deals with the Hald cement data which is a small data set that involves extreme multicollinearity, and the second example deals with the used car prices data which is a large...

Multiple regression can also be non-linear, in which case the dependent and independent variables would not follow a straight line. The multiple regression model allows an analyst to predict an outcome based on information provided on multiple explanatory variables. Still, the model is not always ...
