The package provides a unified\nframework for analyzing such incomplete data, addressing both\ncompletely randomly distributed (Poisson) and spatially\naggregated (Negative Binomial) populations. Key features\ninclude: (1) Adjusted moment-based density estimators for\ncensored distances; (2) Maximum likelihood estimation (MLE) of\ndensity under the Poisson (CSR) model; and (3) Simultaneous MLE\nof density and an aggregation parameter under the Negative\nBinomial model.
