+ (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.")
