时间Sun May 6 10:45:46 2018
大家好,
有一题Clinical Trials(其实也类似实验设计)题目,
苦思许久不知如何下手,来请教大家:
四种treatment: Placebo, drug A B AB(combined treatment)
The gender of each patient was observed
实验开始前, treatment是被随机配置的(每个病人的treatment是随机的)
实验结束後 测量每位病人的疼痛指数 分为 pain & no pain
Dataset如下
center gender treat none pain
1 male P 1 17
1 male A 2 16
1 male B 0 19
1 male AB 0 19
1 female P 6 20
1 female A 6 22
1 female B 3 25
1 female AB 0 26
2 male P 2 18
2 male A 0 19
2 male B 0 20
2 male AB 0 20
2 female P 7 19
2 female A 3 23
2 female B 0 26
2 female AB 0 26
3 male P 5 18
3 male A 1 21

3 male AB 0 25
3 female P 6 16

4 male AB 1 20
4 female P 4 12
4 female A 0 22
4 female B 0 22
