Pairwise Means

 

Menu location: Data_Transforming and Deriving_Pairwise_Means.

 

This function creates a column of all possible (n(n+1)/2) pairwise means within a column:

 

X

2

3

6

 

Means (Within X)

2

2.5

4

3

4.5

6

 

All possible (n(n+1)/2) Xi...(i=1 to n) are averaged with Xj...(j=i to n).

 

These values form intermediate steps in a number of nonparametric statistical methods.
