<blockquote>
  <p>LARS is an extension of the LASSO, which constrains regression coefficients to no more than a possible absolute sum. The LARS algorithm can be understood as recalculating the regression model step by step while slowly relaxing the LASSO constraint. The result of this is analogous to a forward stepwise selection algorithm, but is valid, whereas forward stepwise selection is not. </p>

<p>I have a minor quibble and a major issue:</p>

<ol>
<li>"Recalculating" the regression model -- is the verb appropriate here, or should we say "reestimate" or similar? (I don't know, but it looks suspicious.)</li>
<li>"The result of this is analogous to a forward stepwise selection algorithm, but is valid, whereas forward stepwise selection is not." How is that? In what sense is it analogous? In what sense is it valid? The statement seems to broad to be informative or useful.</li>
</ol>

<p>I hope someone who knows more about LARS will edit the Wiki accordingly.</p>
