Linear regression models a relationship between input variables and an output variable and can be used to predict the value of a response to a new set of inputs. A simple linear regression is a line fitted to existing pairs of one independent variable and a dependent variable, with a parameter designating the slope of the line and a bias the y-intercept. Fitting the line or curve to the data is accomplished by minimizing the error between the observed values and the formulated values using some form of loss function like least squares, ridge regression, or lasso.
Linear regression is a fundamental algorithm used in supervised learning cases because of its simple and well-understood application to a variety of problems like predicting trends in science, healthcare, finance, economics, and consumer behavior. Linear regression supports several estimation techniques, loss functions, and convergence methods to fit different optimization and time/cost goals.
