Box-Cox Question

[#1]

Hello,

I tried to perform a Box-Cox transformation, but got an error because I have 0 values in some of my Y column. My data is tree regeneration density (stems/ha), so some plots had 0 stems in them. Is there a way around this error?

Replace 0 with a very small positive number, such as 0.001, to allow the transform to work.
