Summary

This chapter begins with a discussion on constant detectability over a region. Next, it focuses on estimating detectability. In most situations, the probability of detection would not be known but would be estimated by one method or another. Double-sampling ratio estimation methods apply when an accurate count is made for a subsample of the units surveyed by the usual survey method. Multiple regression methods have been suggested for correcting for imperfect detectability in aerial surveys. The chapter discusses the effect of estimated detectability. It concludes with a discussion on estimated detectability and simple random sampling.
