NettetThe first section in the Prism output for simple linear regression is all about the workings of the model itself. They can be called parameters, estimates, or (as they are above) best-fit values. Keep in mind, parameter estimates could be positive or negative in regression depending on the relationship.

NettetFor instance, x 1(i) is the living area of the i-th house in the training set, and x 2(i) is its number of bedrooms. To perform regression, you must decide the way you are going to represent h. As an initial choice, let’s say you decide to approximate y as a linear function of x: hθ(x) = θ0 + θ1x1 + θ2x2. NettetIn statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable (often called the 'outcome' or 'response' variable, or a 'label' in machine learning parlance) and one or more independent variables (often called 'predictors', 'covariates', 'explanatory variables' or ...

Linear regression plays an important role in the subfield of artificial intelligence known as machine learning. The linear regression algorithm is one of the fundamental supervised machine-learning algorithms due to its relative simplicity and well-known properties.
