Also called simple regression, linear regression establishes the relationship between two variables. Linear regression is graphically depicted using a straight line; the slope defines how the change in one variable impacts a change in the other. The y-intercept of a linear regression relationship...
Linear regression is a supervised machine learning algorithm that is used to predict a continuous value based on a set of independent variables.Whatis regression?Regression is a simple yet powerful technique that can be used to solve a variety of problems, such as predicting house prices, sales f...
