Capture-recapture

=======================Hans-Peter Piepho, 02 May 1997==========ssc Message-ID: <9705021250.AA16056@fserv.wiz.uni-kassel.de> From: Hans-Peter Piepho <piepho@WIZ.UNI-KASSEL.DE> Subject: capture-recapture (2) I recently posted a question regarding capture-recapture, where I presented a "naive approach" to computing confidence limits to estimates of the population size based on log-linear models and asked if the approach was okay. I received no response to the question, but found a paper which does just that, so my question is answered!

Capture/recapture problem.

If you capture n specimens, and there are d types represented, then what is D, the number of types in the wild population? RA Fisher gave an estimation formula in the Journal of Animal Ecology, 1943, Vol 12:42-58. I looked up the article after someone gave the reference online, a year or so ago, and it was readable. * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
