Does JMP still have a function called Exact Wilcoxon Rank Sum test?

Dear Experts,

 

  In the older version of JMP, there is a function called "Exact wilcoxon Rank Sum test" specifically used for nonparametric comparison for small sample size (e.g., n<5). However, in the current version (14.0) I did not see this function any more. Can anyone suggest a new function in the new version with similar or the same power as the "Exact wilcoxon Rank Sum test"?

 

Oneway( Y( :C10 ), X( :Good T1D Vs control ), Wilcoxon Test( 1 ),
	Wilcoxon Exact Test( 1 ) ),

This is the script that I can use in the previous version, but not anymore; it only caculate wilcoxon Test (1) but not the wilcoxon Exact test.

 

Can anyone tell me why?

 

Thanks

 

 

Thanks

For some reason, the current version of my JMP does not have the choice of "Exact test"..

Do you know why?

I have the version of JMP.. But only JMP Pro can do Exact Wilcoxon...I have got confirmation.

I assume your data has more than 2 groups in your Oneway analysis.  The test is only available if the X Factor column only has 2 levels. Below is the documentation taken from the Scripting Index

I found it is still listed in the latest version of JMP:

It still works, too:

I believe that is the software version issue, only the JMP Pro has the exact wilcoxoln. The JMP does not have that...

 

I only have two groups...That is for sure.

 

Well... I hope my bet is correct. If not please suggesst a way to do it in JMP
