WebOrdinary linear regression uses the traditional method of least squares to solve for the model parameters. Regularized linear regression adds a penalty to the least squares method to encourage simplicity by removing predictors and/or shrinking their coefficients towards zero. This can be executed using Bayesian or non-Bayesian techniques. http://mc-stan.org/rstanarm/reference/stan_glm.html
