MCP, KDE, and LoCoH
Three of the most popular methods of home range estimation right now are the minimum convex polygon (MCP), kernel density estimation (KDE), and local convex hull (LoCoH).… Read more “MCP, KDE, and LoCoH”
Local convex hull or LoCoH in R
The local convex hull method of home range estimation is a relatively recent technique. It was developed in 2004 by Getz and Wilmers. You can read the… Read more “Local convex hull or LoCoH in R”
