Let’s explore more on the multiple linear regression in R. On the other hand, linear regression determines the relationship between two variables only. The multiple linear regression in R is an extended version of linear regression that enables you to know the relationship between two or more variables. So, it is inevitable to discover a statistical technique that fits the data and helps determine unbiased results. But the relationship may not always be linear. It helps to determine the relationship and presume the linearity between predictors and targets. It is a type of regression method and belongs to predictive mining techniques. Multiple linear regression is one of the data mining methods to determine the relations and concealed patterns among the variables in huge. Multiple regression is of two types, linear and non-linear regression. The multiple linear regression enables analysts to determine the variation of the model and each independent variable’s relative contribution. The variable to be predicted is the dependent variable, and the variables used to predict the value of the dependent variable are known as independent or explanatory variables. It is an extension of linear regression and also known as multiple regression. Multiple linear regression is a statistical analysis technique used to predict a variable’s outcome based on two or more variables.

When there are two or more independent variables used in the regression analysis, the model is not simply linear but a multiple regression model. Linear regression models are used to show or predict the relationship between a dependent and an independent variable.
