 AB    The usage of tree-structured or recursive partitioning methods has grown
       steadily in the decade since the appearance of the definitive monograph
       'Classification and Regression Trees'. Accompanying this growth have
       been many methodologic and software extensions that have served to give
       the tree-structured approach even wider applicability. This overview
       highlights some of these developments, emphasizing the regression
       setting. An illustrative example describes how tree-structured
       regression, modified to handle right-censored, left-truncated survival
       data with time-dependent covariates, can be used to assess whether rates
       of progression from HIV to AIDS have changed over time.
