WebApr 1, 2000 · This detection probability applies to each of the point counts (or stops) on the route for which it is estimated, and thus to each area (i = 1, 2) and the entire area sampled by the counts. Thus, the distribution of (x 11 + x 21) is B(N 1, p), and that of (x 22 + x 12) is B(N 2, p). WebEffects on parameters of detection probability are specified with R formulae using standard variable names or named covariates supplied by the user.
