Beginning at a value of 1 (no collinearity), a VIF between 1–5 indicates moderate collinearity while values above 5 indicate high collinearity.

The VIF measures how much the variance of an explanatory variable increases due to multicollinearity . A high VIF value indicates a high degree of multicollinearity. The formula for calculating the VIF of an independent variable x is:

If a dummy variable represents more than two categories with a high VIF score, multicollinearity might not exist. If there is a fragment of cases in a given category, the variables will always give high VIF values.
WebNov 3, 2024 · Any variable with a high VIF value (above 5 or 10) should be removed from the model. This leads to a simpler model without compromising the model accuracy, which is good. Note that, in a large data set presenting multiple correlated predictor variables, you can perform principal component regression and partial least square regression ...
WebNov 12, 2024 · First, we should produce a correlation matrix and calculate the VIF (variance inflation factor) values for each predictor variable. If we detect high correlation between predictor variables and high VIF values (some texts define a “high” VIF value as 5 while others use 10) then lasso regression is likely appropriate to use. js 配列 追加 キーWebNov 7, 2024 · The rules of thumb for determining whether your VIF is a concern are: 1 = not correlated Between 1 and 5 = moderately correlated Greater than 5 = highly correlated Most statistical software displays the VIF in the regression output.

That number also represents how much a variable is inflated because of the linear dependence with other variables. The VIF value starts from 1, and it has no upper limit. If the number gets larger, it means the variable has huge multicollinearity on it. js 金額 カンマ
