R build linear regression model
WebLinear 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.
