Re: [R] median by geometric mean -- are we missing what's important?

Yes, of course. I think all the posts up to Bert's addressed the coding question as asked - how to calculate a particular version of the median (not the mean) rather than any underlying, unstated, statistical or scientific question. IIRC there hasn't been any indication that non-positive values

Re: [R] median by geometric mean -- are we missing what's important?

Folks: I know this may be overreaching, but are we missing what's important? WHY do the zeros occur? Are they values less then a known or unknown LOD? -- and/or is there positive mass on zero? In either case, using logs to calculate a geometric mean may not make sense. Paraphrasing Greg Snow, what
