Hi all,
Assume that I have the following 10 data points.
x=c( 46, 125 , 36 ,193, 209, 78, 66, 242 , 297 , 45)
sort x and get the following
y= (36 , 45 , 46, 66, 78, 125,193, 209, 242, 297)
I want to group the sorted data point (y) into equal number of
observation per group. In this case there will be three groups. The first
two groups will have three observation and the third will have four
observations
group 1 = 34, 45, 46
group 2 = 66, 78, 125
group 3 = 193, 209, 242,297
Finally I want to calculate the group mean
group 1 = 42
group 2 = 87
group 3 = 234
Can anyone help me out?
In SAS I used to do it using proc rank.
thanks in advance
Val
