Webb23 maj 2024 · In Simple Linear Regression (SLR), we will have a single input variable based on which we predict the output variable. Where in Multiple Linear Regression (MLR), we predict the output based on multiple inputs. Input variables can also be termed as Independent/predictor variables, and the output variable is called the dependent variable. Webb00:55 And the linear regression object is going to be expecting for the input array a two-dimensional array.
