I met a problem to test a nested design with 4 levels. There are one fixed
effect x1.
random effects are nested A, B(A), C( B*A)
For each subgroup C, there are D repeated measurements.
I need to estimated the variance within each subgroup C. Also
I want to test for each subgroup B, the variance within subgroup C
heterogeneous or not?
To estimate the variance within C, here is my code:

规章制度不知道啊,科学上说,如果用Bonferroni弄过的P value是可以的。比如总共
有100种subgroup可能性,那么某一个subgroup的P value达到0.0005可以说得过去。

请问一下:如果A=B+C, 如果想比较A和B, 因为B是A的subgroup, 怎么比较? t test
好像是不行,因为两个不是独立的。有什么方法吗?怎么说A和B有显著不同呢?

Design structure is like this:
level A : 1 2 .... 5
level B : a b c d l m
level C: x y z
level D repeat: 1 1 1
2 2 2
3 3 3

So all levels A, B, C are random and D is repeat
I thought the first code is more suitable for estimation of the variance
within each subgroup C ,for each group B. I might messed up here.

当然可以
不过不是prospective study的话
fda基本不大可能approve
你可以另外做一个新的study证明你的效果好
毕竟很多study收集n个变量
总能够发现一两个subgroup是统计显著的

你的这个“必须”的定义是什么?是指的FDA的drug market approval么?如果是的话
,你可以想象FDA愿意让一个subgroup analysis的statistical significance就通过一
个药品去市场流通么?
在一个trial里面有个ad hoc发现,倒是可以个重新开一个trial做一个很好的理由,
FDA或许会同意。要知道,报告一个好的protocol也很重要,没有充分的理由,从伦理
学角度出发FDA也不会顺便同意一个药厂开一个trial,即使你很任性想砸钱。。。

是这样,首先我觉得你是在说 advanced subgroup。
在 advanced subgroup 里,小学公开数据跟大学的 correlation 不太好的原因,是因
为小学的成绩本身主要看 participation,而忽略了 advanced group 里最重要的两条
:(1)精读时获取 deep 而仅仅是 shallow knowledge 的能力,(2)泛读的速度。
泛读长期是用来过滤信息的,speed kills。短期而言是给娃建立知识树主干的,speed
also kills。
另外我认为真正意义上智商高的,通常统计上 neuroplasticity 也高,这样 miss 一
点点 critical period 的影响相对较小。
当然对于 advanced group,我更多是观察猜测,能找到的研究很少。

Is it a problem of a take-home test? If yes, stop here.
If |G|=72=2^3*3^2, consider its sylow 3 subgroups.
G has either 1 or 4 sylow 3 subgroups.
If 1, this sylow subgroup is normal.
If 4, consider the map f:G->S(4), that maps each g in
G to a permutation of the set of this sylow subgroups
by conjugation. Since |S(4)|=24, and f is not constant,
3<=ker(f)<24, which is a notrivial normal subgroup.

那段文字是新法案建议在原来的旧法律中增加一条,原来的旧法律是 28A.300 RCW,这
是一条关于 superintendent 的职责的法律,所以你要探究 subgroup 的意思,就必须
把这段文字放在 28A.300 RCW 的里面去看,看看它放在这个 context 里是什么意思,
对吧?
我懒得去看整条(非常多),我就这么假设:因为这是一个已经存在的法律,如果里面
有任何种族不恰当的条文,早就被揪出来了!毕竟那是华盛顿州。所以我不相信当
Subgroup 放在里面时,会是指种族。当然,同样地,我们必需明确在该条法律里面

积分相同才开始这么比较.
然后当然是相互间净胜球,进球数.
当然,背后的意思就是这同分球队组成一个subgroup,然后排名。
具体直接点,就是因为积分相同,只能通过相互净胜球,进球数排名。
现在欧足联规则有点歧义的地方是:
如果三支球队a,b,c同分,组成subgruop1,排名。
这时候,如果a第一,b,c仍然比较不出排名。
那么,是继续递归调用subgroup算法,
就是说b,c组成subgroup2比较;
还是break出来,结束subgroup比较,直接比较整个group排名。
我比较倾向继续subgroup比较.这个也是新浪给出的中文版本规则。
