WebMultiple Linear Regression Model We consider the problem of regression when the study variable depends on more than one explanatory or independent variables, called a multiple linear regression model. This model generalizes the simple linear regression in two ways. It allows the mean function E()y to depend on more than one explanatory variables Web11 iul. 2024 · The equation for this problem will be: y = b0+b1x1+b2x2+b3x3. x1, x2 and x3 are the feature variables. In this example, we use scikit-learn to perform linear regression. As we have multiple feature variables and a single outcome variable, it’s a Multiple linear regression. Let’s see how to do this step-wise.
