calculate.mean.detection.prob

The detection function parameters. A single value for halfnormal, or a vector of two values for hazard rate.

theta

The maximum range of observation. Objects at distance greater than w from the observer are assumed to never be recorded.

The detection function. Only "halfnormal" and "hazard" (hazard rate) are supported at present.

detection.function


Calculates the mean detection probability over the range of observation.


Calculates the study size (either number of detections, or
proportion of region that should be covered) to achieve a target precision for
the estimated abundance. The calculation allows for the penalty due to unknown
detection function, and for overdispersion. The user must specify a guess at the
true detection function.

calculate.mean.detection.prob: Mean detection probability.
