I have sent you the data set last Sunday. I have organized the data as per the requirement of DENSITY.
The goal is to estimate the density of the animal. But failing in running the estimate. I request your help in this regard.

Hello Kumara
It appears you are addressing me. Unfortunately I do not have time for every enquiry. You could post a specific question here, perhaps with data, and hope that someone else answers. Or you could seek help from a colleague in your field.
