WebThe l2boost package implements a generic boosting method [Friedman (2001)] for linear regression settings using an l2-loss function. The basis functions are simply the column vectors of the design matrix. l2boost scales the design matrix such that the boosting coefficients correspond to the gradient direction for each covariate.
