Hello,
I'm using JMPpro for reliability data analysis.
I understand that "fit life by X" tool can be used for ALT data analysis and the "relationship" seems to show an accelerated test condition-lifetime relationship(Arrhenius, Linear etc.).
What is "Location" and "no effect"?

JMP help document says: Location means that μ is different for every level of X
Does this mean that it is used when there is an accelerated condition-life relationship (ALT data) but the specific relationship is unknown, or does it mean that it can be used even if the accelerated condition-life relationship is not existed? (not ALT data)
And for "no effect", I cant find any clue.

Thank you.
