The isotonic median regression problem arises from statistics. An algorithm, the PAV algorithm, has been proposed for solving this problem since 1980. In this paper, we propose two kinds of data structures for efficiently implementing the PAV algorithm. The running time of the algorithm is also impr

✦ Synopsis
Using a few very basic observations, we take fllll advantage of the special structure of the l ~c regression problem to obtain a direct and finite algorithm for the computation of the l °e regression line. The complexity of the algorithm and the computational results showing the effectiveness of the algorithm will also be presented. O 2001 Elsevier Science Ltd. All rights reserved.
