This means that the model can be interpreted using a straight line. But how do we know what the line looks like? This is where linear regression comes into play! NettetLinear models can be used to model the dependence of a regression target y on some features x. The learned relationships are linear and can be written for a single instance i as follows: y = β0 + β1x1 + … + βpxp + ϵ. The predicted outcome of an instance is a weighted sum of its p features. NettetThe most popular form of regression is linear regression, which is used to predict the value of one numeric (continuous) response variable based on one or more predictor variables (continuous or categorical).
