WebThe bounded-count method (Section 9.2.2) and the binomial sampling model of Overton (1969) (Section 9.2.3) attempt to estimate abundance without the need for distance information. The Overton (1969) method should generally be avoided and the bounded-count method should be used only when detection probabilities are known to be extremely high. WebC t f t = q(N 0 K t 1) C t f t = qN 0 qK t 1 (3) The last expression of (3) is in the form of a linear model (Figure1) where C t f t is the response variable, K t 1 is the explanatory variable, qis a constant (i.e., the slope), and qN 0 is a constant (i.e., the intercept) because it is the product of two constants.
