My question is when I pull the data for covariates in survival modeling,
should I only pull the covariates value for each individuals before the
origin of time I chose since survival analysis usually consider the
prospective followup or I can pull the covariates during the followup period
? Thanks.

发帖数: 231 | 3 我用以下的SAS code作Survival Curve:
proc lifetest data=models plots=(s) cs=none graphics;
time duration*event(0);
strata age1;
run;
比较讨厌的情况是output plot中的legend没法编辑，结果图表中的horizontal axis
title和variable legend都是按照输入的数据的原本模样。还有其他一些讨厌的地方。
请问有什么办法可以改善这种状况? 我现在用的是SAS9.2.
我能想得出来的是将survival function output拷到Excel中，然后完全让Excel来做
graph。但问题是数据的样本很大，case非常多，没办法简单的copy and paste。
所以请高手予以指教. 多谢多谢! |

一篇文章: duration dependence in stock prices: an analysis of bull and bear
markets 采用了survival analysis 来预测股市什么时候进入牛市，什么时候进入熊市
。一些hedge fund采用了这个strategy。 有人愿意讨论一下吗？
survival analysis跟 point/counting/renewal process有什么联系呢？
有人可以推荐相关文章或者书籍吗？

发帖数: 790 | 5 in general, if you will handle time to event data, it is likely you will
want to check survival methods.
and you will have time to event data in almost every field.
my personal opinion, survival and clinical trials are two of the most
biostatistical courses/fields. |

发帖数: 182 | 6 If you want to do survival analysis on clinical data, try this book:
Survival Analysis by John P. Klein and Melvin L. Moeschberger.
Read the most recent edition, since there are many mistakes in the old ones.
This book is not the greatest. But it is easy to understand and focus on the
application. Also be aware that it is mostly on semiparametric/
nonparametric approch. You may want some other books if you want to learn
the parametric approach.

Google "stat textbook" and "UCLA". The resulting website offers lots of SAS

There are so many situations when collecting survival data. Left, right,
interval censoring. Left, right truncation. Each case corresponds to a
component in likelihood construction. It may be better to refer to a real
textbook, rather relying solely on a SAS book.

一个医学study, 我用PROC LIFETEST生成了Survival curve，但是因为观测的时间比较

发帖数: 1433 | 14 你要每个individual整个的predicted survival curve的话，在newdata里只要加上
covariates就行，去掉individual=TRUE. For example, pred<-survfit(model,

发帖数: 3942 | 17 没做过marketing，
不过所有survival analysis的应用应该都差不多--
user attrition是一个event，
用一般的classification方法可以用来预测event occurrence within a certain
width of period
用survival就可以用来预测when the event will occur
logistic regression可以视为Cox model with exact/discrete time treatment of
tied events的特殊形式 |

发帖数: 273 | 18 恩，以前老考虑sensoring,所以忘了survival analysis其实有两大特点：
一个是 可以处理sensoring
另一个是可以处理时间
不过我觉得survival analysis主要不是用来预测when the event will occur的，特别
是作为semi-paramatric的cox model.应该主要是用来比较不同factor对event发生概率
的影响（比率）。引入的时间项h(t)是unspecific的，因此求解中消掉了好像。不知对
不对。有大牛说说。 另外，需要提醒的是它的exp项是没有intercept的。这个是与
logistic regression重要的不同的之一。 |

In 1966, an SR-71 “Blackbird” disintegrated at 78,000 feet. The pilot’s
first thought was “No one could live through what just happened”. SR-71 is
