In the meanwhile, supported by a rich body of statistical inference, OLS has become the core of the regression analysis. Whereas theoretically explanatory variables are assumed independent implicitly in most, if not all, linear models, the analysis proceeds with data given exogenously in practice. ...
In this approach, often referred to as path analysis, regression is used to describe an entire structure of linkages that have been advanced from a causal theory. Multiple regression is an extension of the bivariate linear regression presented in Chapter 18. Although dummy variables (nominal ...

Calculation and analysis The VIF can be calculated and analyzed in three steps: Step one Calculatekdifferent VIFs, one for eachXiby first running an ordinary least square regression that hasXias a function of all the other explanatory variables in the first equation. Ifi= 1, for example, the...
In statistics, the variance inflation factor (VIF) quantifies the severity of multicollinearity (多重共线性)in an ordinary least squares regression(普通最⼩⼆乘回归) analysis. It provides an index that measures how much the variance (⽅差)(the square of the estimate's standard deviation (...
We’ll use the Boston data set [in MASS package], introduced in Chapter @ref(regression-analysis), for predicting the median house value (mdev), in Boston Suburbs, based on multiple predictor variables. We’ll randomly split the data into training set (80% for building a predictiv...

A variance inflation factor (VIF) is a measure of the amount of multicollinearity in regression analysis.Multicollinearityexists when there is a correlation between multiple independent variables in a multiple regression model. This can adversely affect theregressionresults. Thus, the variance inflation fa...
