I'm very new to JMP and i'm exploring the possibilities with example found here and there on the net.
One thing i can't get to perform correctly is the Wilcoxon signed rank test.
I'm trying to follow the example given in this link :http://www.statstutor.ac.uk/resources/uploaded/wilcoxonsignedranktest.pdf
I'm going through "fit y by x" and selecting one column in y and one in x then non-parametric>Wilcoxon
The results is not the one given in the link nor the one calculated by hand.
It appaears the signed rank test is not the test that JMP is performing.
My suspicion is that it does not recognize paired data
Any help on this subjects would be greatly appreaciated
Have a great day,

It should look like this when you get it correctly:

First, both variables must be numeric and continuous. (The Before variable is currently nominal.)
Second, select Analyze > Specialized Modeling > Matched Pairs. Be sure to enter the Before variable in the Y role, then the After variable.
See how that approach works.
Thank you for this quick and spot-on answer.
It seems so easy now that it's explained
With any luck it will help someone else in the future
Have a great day :)
