If we measure the radial distances (r) to each animal seen (see Figure 5.2),

Eberhardt (1978a) has shown that the

For example, suppose that you wish to have a

**coefficient of variation**of density of

about + 10% so that the 95% confidence interval is about +20% of the population

size. A pilot study has determined that b = 2. From equation (7.21), CV(0) = ...
