Box-Cox transformation with 0 values

Dec 5, 2019 05:30 PM (2832 views)

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 the 0 values with very small positive values, such as 1e-6? (I don't know the range of your regeneration density response.)
