summary

summary,apss-method

summary,Tree-method

an object of S4 class <code>apss</code> or <code>Tree</code>.

object

a scalar object to determine the number of subgroups K. If missing, the estimated subgroup K is selected.

This function provides tabloid information such as survival median, 1-, 3-, and 5 years actual suvival time for each terminal group as a table format.

methods

This package provides some routines to conduct the
        K-adaptive parititioning (kaps) and recursive partitioning
        (lrtree) for survival data, with the application to SEER
        (Surveillance Epidemiology and End Results). A function kaps is
        an implementation version of our algorithm kaps which provides
        minimax based partitioing rule by log-rank test. A fuction
        lrtree enables researchers to conduct log-rank survival tree
        proposed by Segal (1988). In the near future, we have a plan to
        add new recursive partitioning algorithm for survival data
        called STUDI (Cho and Hong, 2008)
