st: Loop to compare several variables within different timepoints
Date

I have about 25 variables for which I recorded outcomes at 3 times
points (t1, t2, t3)
I would like to construct a loop where I can automate testing using
the "signrank" test
I would like to do the following:
signrank a1=a2
signrank b1=b2
signrank c1=c2
.....
signrank a3=a2
signrank b3=b2
signrank c3=c2
..............
a,b,c are the variables and 1,2,3 refer to the timepoints
I am only interested in 25*2=50 comparisons and not to compare
different letter variables between them. Only within the same
variables to compare between timepoints.
Any help would be appreciated.
Thank you,
Nick
