Friedman post hoc analysis

Question

I received a question on what Post Hoc tests are available for the Friedman test.  Looks like the same customer posted this question back in May on the Community (Friedman post hoc analysis - JMP User Community).

I was looking through the attached paper and saw the below comments. Is the Tukey HSD option something to recommend here?

Thanks Jed! I also just came across this recent JMP Devlopment update and saw a note that a few new post hoc tests are coming in a future version that are specific to the Friedman test.

Looking forward to this, @jianfeng_ding . Thank you!

I'm not entirely certain I understand the question the customer is asking, so here are 2 potential answers:

1. Yes, Tukey's HSD is a post hoc analysis tool available in JMP (source).

2. Many practitioners recommend it, as it is more sensitive to differences in sample sizes. I know some people that use it exclusively (instead of a student's t test) and some who use it in conjunction with the other means comparison tests in the same menu.
