Chapter 6 Other topics
In this chapter we provide an extended demonstration of importing data in program Distance, as well as the files so you can try importing. Multipliers are useful when you wish to compute density of inanimate objects (such as dung piles, ape nests or sounds such as bird calls or whale vocalisations) and convert these densities into animal density (by incorporating estimates of production and decay rates). We present a short overview of other extensions of distance sampling that can be performed with program Distance.

Multipliers in conjunction with lure survey (advanced)
- Lure surveys cannot be analysed using Distance for Windows. An example of analysing such data from a survey of Scottish crossbills (described in the multipliers lecture slide 21)
