[jira] [Commented] (SPARK-8518) Log-linear models for survival analysis

["Xiangrui Meng (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-8518?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14725732#comment-14725732 ] 

Xiangrui Meng commented on SPARK-8518:
--------------------------------------

The value in this column would be 0/1. Then we need to see how users would interpret `event = 1` and `event = 0` vs. `censored = 1` and `censored = 0`. The latter looks easier to understand to me. Users do not need to visit the doc to see what `event = 1` means.

> We want to add basic log-linear models for survival analysis. The implementation should match the result from R's survival package (http://cran.r-project.org/web/packages/survival/index.html).
