Multiple regression is a statistical tool used to derive the value of a criterion from several other independent, or predictor, variables. Multiple linear regression is the most common form of linear regression analysis. It does this by simply adding more terms to the linear regression equation, with each term representing the impact of a different physical parameter. A Multiple linear regression (MLR) is a statistical technique, usually multivariate, which is used in examining the relationship between the explanatory and response variables. Multiple linear regression makes all of the same assumptions assimple linear regression: Homogeneity of variance (homoscedasticity): the size of the error in our prediction doesn’t change significantly across the values of the independent variable.

For example, you could use multiple regr… Hence as a rule, it is prudent to always look at the scatter plots of (Y, X i), i= 1, 2,…,k.If any plot suggests non linearity, one may use a … Multiple regression model allows us to examine the causal relationship between a response and multiple predictors. The case of one explanatory variable is called simple linear regression. Multiple Linear Regression So far, we have seen the concept of simple linear regression where a single predictor variable X was used to model the response variable Y. The process is fast and easy to learn. Multiple regression is a statistical tool used to derive the value of a criterion from several other independent, or predictor, variables.
