"<html><head/><body><p>Least-angle regression (LARS) is a "
"regression algorithm for high-dimensional data, developed by "
"Bradley Efron, Trevor Hastie, Iain Johnstone and Robert "
"Tibshirani. LARS is similar to forward stepwise regression. "
"At "
"each step, it finds the predictor most correlated with the "
"response. When there are multiple predictors having equal "
"correlation, instead of continuing along the same predictor, "
"it proceeds in a direction equiangular between the "
'predictors.</p><p><span style=" font-weight:600;">The '
"advantages of LARS are:</span></p><p>It is numerically "
"efficient in contexts where p >> n (i.e., when the "
"number "
"of dimensions is significantly greater than the number of "
"points)</p><p>It is computationally just as fast as forward "
"selection and has the same order of complexity as an "
"ordinary "
"least squares.</p><p>It produces a full piecewise linear "
"solution path, which is useful in cross-validation or "
"similar "
"attempts to tune the model.</p><p>If two variables are "
"almost "
"equally correlated with the response, then their "
"coefficients "
"should increase at approximately the same rate. The "
"algorithm "
"thus behaves as intuition would expect, and also is more "
"stable.</p><p>It is easily modified to produce solutions for "
'other estimators, like the Lasso.</p><p><span style=" '
'font-weight:600;">The disadvantages of the LARS method '
"include:</span></p><p>Because LARS is based upon an "
"iterative "
"refitting of the residuals, it would appear to be especially "
"sensitive to the effects of noise. This problem is "
"discussed in "
"detail by Weisberg in the discussion section of the Efron et "
"al. (2004) Annals of Statistics article.</p></body></html>"
