Linear regression is the most basic and commonly used predictive analysis. Regression estimates are used to describe data and to explain the relationship between one dependent variable and one or more independent variables.
Any pair of independent variables may not be highly correlated, but one variable. may be a linear function of a number of others. In a 3-variable regression, multicollinearity is the correlation between the 2 explanatory variables.
