Nettet4. mar. 2024 · Multiple linear regression analysis is essentially similar to the simple linear model, with the exception that multiple independent variables are used in the model. The mathematical representation of multiple linear regression is: Y = a + b X1 + c X2 + d X3 + ϵ. Where: Y – Dependent variable. X1, X2, X3 – Independent (explanatory) variables. Nettet21. jun. 2024 · Linear models with more than one input variable p > 1 are called multiple linear regression models. The best known estimation method of linear regression is the least squares method.
