How to understand Lambda1 and Lambda2 for Box Cox transformation ?

Created: Mar 21, 2023 04:25 AM  |  Last Modified: Jun 8, 2023 5:59 PM (1189 views)

What do Lambda1 and Lambda2 mean when specify parameters for Box Cox transformation? How to specify them?

I have searched Box Cox formula in Help. It has only one Lambda parameter in formula. So I'm confusing.

Thank you!

JMP's Box-Cox function (as opposed to the B-C transformation in linear models, as you show above) is based on the following.
