sensorial analysis<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

Hello,

I have a discussion with a customer related to sensorial analysis.

She named me 2 comparison mean test that I didn't find in JMP (neither in File Exchange): NewMann Keulls, PLSD Fisher

It seams that there are tests for multiple comparison.

Did you already heard about this tests in the past? How would you compare them to those in JMP (Hsu, Tukey, etc)?

What is your usual message in this situation?

Thank you,

Florence

Florence,

Ce sont tous deux des tests de comparaison multiples. Voici un lien vers un article comparant Tukey et Newman-Keuls: https://www.utdallas.edu/~herve/abdi-NewmanKeuls2010-pretty.pdf . Pour autant que je sache, PLSD Fisher est le test de Fisher que nous avons dans JMP, mais appliqué uniquement si le H0 global est significatif (le «P» signifie «Protected»).
