(synopsis "Least angle regression software")
(description
"Least Angle Regression (\"LAR\") is a model selection algorithm; a
useful and less greedy version of traditional forward selection methods. A
simple modification of the LAR algorithm implements Tibshirani's Lasso; the
Lasso modification of LARS calculates the entire Lasso path of coefficients
for a given problem at the cost of a single least squares fit. Another LARS
modification efficiently implements epsilon Forward Stagewise linear
regression.")
