# multicollinearity

## Summary

Multicollinearity is a phenomenon in which one predictor variable in a multiple regression model can be linearly predicted from the others with a substantial degree of accuracy. 1 It occurs when independent variables in a regression model are correlated 2 3 , and can result in less reliable statistical inferences. 2 The term was first used by Ragnar Frisch. 4

Summary In statistics , multicollinearity (also collinearity ) is a phenomenon in which one predictor variable in a multiple regression model can be linearly predicted from the others with a substantial degree of accuracy

Summary Multicollinearity is a statistical concept where several independent variables in a model are correlated. Two variables are considered to be perfectly collinear if their correlation coefficient is +/- 1.0. Multicollinearity among independent variables will result in less reliable statistical inferences.

Summary Multicollinearity occurs when independent variables in a regression model are correlated. This correlation is a problem because independent variables should be independent . If the degree of correlation between variables is high enough, it can cause problems when you fit the model and interpret the results.

Summary The term multicollinearity was first used by Ragnar Frisch. It describes a perfect or exact relationship between the regression exploratory variables. Linear regression analysis assumes that there is no perfect exact relationship among exploratory variables.
