Webb30 apr. 2024 · Variance Inflation Factor (VIF) Variance inflation factor (VIF) is a technique to estimate the severity of multicollinearity among independent variables within the context of a regression. It is calculated as the r atio of all the variances in a model with multiple terms, divided by the variance of a model with one term alone . Webb13 apr. 2024 · Dimensionality reduction is a technique used in machine learning to reduce the number of features or variables in a dataset while preserving the most important information or patterns. The goal is to simplify the data without losing important information or compromising the performance of machine learning models.

WebbUse Variance Inflation Factor. The Variance Inflation Factor is the measure of multicollinearity that exists in the set of variables that are involved in multiple regressions. Generally, the vif value above 10 indicates that there is a high correlation with the other independent variables. Let us have a look at a program that shows how it can ... WebbIn this article, you learned about the difference between correlation, collinearity, and multicollinearity. In particular, you learned that multicollinearity happens when a feature exhibits a linear relationship with two or more features. To detect multicollinearity, one method is to calculate the Variance Inflation Factor (VIF).
