ConfidenceRange
ConfidenceRange
是 SurvivalModelFit 和其他函数的一个选项，它指定同步计算置信区间和置信带的范围.
更多信息
- ConfidenceRange 影响与同步置信区间和置信带的相关属性的值.
- ConfidenceRange 的可能设置包括：
-
All 使用非删截数据的区间 Full 使用数据的全部范围 {tmin,tmax} 显式设置置信区间 - 数值 tmin 和 tmax 可以是任何满足 tmin<tmax 的实数.
- 对于事件时间为 et 的生存模型，设置 Full 等价于设置 {Min[et],Max[et]}.
- 设置 All 等价于设置 {Min[nc],Max[nc]}，其中 nc 是非删截和区间删截数据值的端点.
