Explanation:
Detailed explanation-1: -When more than one predictor is used, the procedure is called multiple linear regression. When we fit a multiple linear regression model, we add a slope coefficient for each predictor. For the Cleaning example, with OD and ID as predictors, the model has slope coefficients for both predictors.
Detailed explanation-2: -The multiple regression model is based on the following assumptions: There is a linear relationship between the dependent variables and the independent variables. The independent variables are not too highly correlated with each other. yi observations are selected independently and randomly from the population.
