之前看到一篇文獻說 存活分析可以檢定固定時間 兩組的survival rate是否有差 這樣的檢定要如何做? 可以用sas的語言辦到嗎 謝謝您! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.116.116

A test statistic can be obtained by comparing the K-M

You may just use SAS to calculate the K-M estimator

and print out the corresponding standard error at each

time point.You may then calculate the value of the
