Thus one could use linear regression techniques to

**obtain**an estimate of the

slope (1/N) and thus an estimate of population size. The appropriate formula for

this estimation is X (C, M%) W = H (2.13) 2. (R,M,) where s = Total number of ...

For example, from Table 2.7 the size of the “marked” population at time 6 is 2 (78

+ 1)(4) = —- + - - M6 66 + 1 57 = 61.72 The proportion of “marked” animals is

**obtained**from _ m, # 1 al n, + 1 (2.41) For example, from Table 2.7 57 -- 1 ^ - = =

Cochran (1977, 98) has shown that with optimal allocation, the theoretical

expectation is that S.E.(optimal) < S.E.(proportional) < S.E.(random) where S.E.(

optimal)= Standard error of the stratified mean

**obtained**with optimal allocation of
