Meaning of lrv and interpreting negative rho values... #20

Closed lix2k3 closed 3 years ago

lix2k3 commented 3 years ago

This package has been very helpful. I have two questions: Do the FDR cutoffs also apply to the negative rho values, such that a cutoff of .25 applies to rho values below -.25? The basis of that question is that a rho of -.70, for example, should imply significant reciprocality and we'd want to know if it's trustworthy?

And, what is the meaning of "lrv," and how do we generally interpret it.

Hi lix2k3! I'm glad you've found propr useful.

"LRV" means log-ratio variance (equivalent to variance of the log-ratios = vlr).

As for your other questions, I think you will find the answers here --
