[RESOLVED] Box Cox transformation

Post by Zemb »

Hi,
first time poster here. Is there a way to run a Box Cox transformation in Jamovi ?

Thanks in advance.

Hi,

Not yet. I think you need either an IFELSE() function or a specialized function to do this (and we haven't implemented either yet). It's best to make an issue on github to remind us of this request: https://github.com/jamovi/jamovi/issues.

Cheers,
Ravi

Having looked into it a bit more I think it really depends on whether you want to define a lambda yourself or use the lambda with the greatest log-likelihood. The former you can already do, while the latter needs a specialized function.

I was looking at the greatest log-likelihood :).
