What are some statistical methods used to analyze density-dependent relationships in ecological data? Are there any density-dependent factors that can have positive effects on a population?

Density-dependent factors are environmental influences that depend on population size or density, such as competition for resources, predation, and disease. Density-dependent factors change in intensity based on population size, acting as a form of population regulation, while density-independent factors can cause ...
