What are requirements to perform Wilcoxon test in JMP

[#1]

Are there any requirements to data distribution shape or variance to perform Wilcoxon test in JMP? 

Thanks

[#2]

This is a non-parametric test, so it makes no assumptions about the distribution. It is 'distribution-free.'

[#3]

Are your groups matched pairs, or are they from independent groups?

[#4]

The data are from independent groups. 

I would like to know if any requirements for variance between the two groups, equal vs non-equal?

[#5]

The data should be of equal variance and the measurement system should be of equal interval, but the distribution does not have to be normally distributed.

[#6]

Thanks. Which function in JMP could be used if the data are not normal distribution and variance not equal?

It surprises me that a search for Wilcoxon in documentation returns multiple hits:

https://www.jmp.com/support/help/en/18.0/#search/Wilcoxon

I only knew may be a couple.

A read of some of them reveals two questions: what you data look like, and what is your hypothesis?

Here are some of the relevant hits:

All responses from Mark and Jim are relevant. But I think you need to read through those documentations and find the one that is appropriate for your situation.
