distance.sample.size (version 0.0)

Calculates Study Size Required for Distance Sampling

Description

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.
