标 题: compare the deviation of data points in two different group
发信站: BBS 未名空间站 (Tue Jun 22 18:39:17 2010, 美东)
suppose I have two groups(A,B) measuring the stock price with the same unit.
and I have a data point A1 in group A and a data point B1 in group B. The
distributions of group A and B are not known and are different.
Is there any way I can compare which point deviates larger from its group
center(mean or median)?
Assume there is no out

its mean.
