Linear regression code
NettetIn the above code, we have used a fit() method to fit our Simple Linear Regression object to the training set. In the fit() function, we have passed the x_train and y_train, which is our training dataset for the dependent and an independent variable. Nettet26. sep. 2024 · Taken together, a linear regression creates a model that assumes a linear relationship between the inputs and outputs. The higher the inputs are, the higher (or lower, if the relationship was negative) the outputs are. What adjusts how strong the relationship is and what the direction of this relationship is between the inputs and …
