I'm a Master degree student currently working on a project of estimating the abundance of Long-tailed Macaque on the whole island of Bali.
For this purpose, we collected data using Point Distance Sampling and recorded all monkeys on a 50m radius. We visited different sites across the island (5 lines of 5km and 9 points per line so 45 points per site in total).
I tried different analysis and followed your very detailed and well explained online course but I can't seem to find what would be the most appropriate way of analysing this data. I tried analysing it as single observations but as macaques live in groups, cluster analysis seems more appropriate to me.
Any advices ?
