All appendices have now been revised. </p> <p> An error in Theorem 2.4 in the main body of the paper has been corrected: While storage statements previously stated were asymptotically correct the multiplicative constant in the original statement of the theorem was not. A more modest claim, providing an asymptotic bound on storage requirements, is now provided. </p> <p> The statement of Lemma 4.2 has been corrected — to indicate that w<sub>1</sub> = A⋅w, and not A⋅w + b: The claim would be false without this change. </p> <p> Finally, a typographical error in the bounds on expectations included in Lemma 6.1 has been corrected (the bounds are actually significantly better than as indicated in the original version of this report). </p> </li> </ul> <br /> <h1>Links:</h1> <ul> Warning: fopen(/home/profs/eberly/www/eberly_links.txt): failed to open stream: No such file or directory in /home/profs/eberly/www/includes/noframe_links.php on line 4 Warning: file(/home/profs/eberly/www/eberly_links.txt): failed to open stream: No such file or directory in /home/profs/eberly/www/includes/noframe_links.php on line 6 <li> <p> [ <a href=""></a> ]: </p> </li> </ul> </body>
