How to prove the test statistic of the Wilcoxon signed rank test is symmetric about its mean?
I know that if I want to prove a distribution is symmetric, I need to show
$f(m-t)= f(m+t)$ but $W$ doesn'...

Prove the relationship between Walsh averages and Wilcoxon signed rank test
In my lecture notes it is stated that
sum of all positive signed ranks (defined in Wilcoxon signed rank test) = the number of Walsh averages that are greater than median
How can I prove this ...
