In statistics, multicollinearity (also called collinearity) is a phenomenon with the help of which two or more predictor variables in a multiple regression model can be described as highly correlated, this means the one can be linearly predicted from the others with a substantial degree of accuracy.
Multicollinearity helps to describe the high correlations of 2 or more independent variables. It is used to accurately know the effects of independent variables with the used of regression analysis. The most direct test for multicollinearity is available in linear regression.
