title: 'TruncatedPCQM: Density Estimation for Point-Centered Quarter Method with Truncated
  Sampling'
version: 0.1.2
doi: 10.32614/CRAN.package.TruncatedPCQM
abstract: 'Implements a systematic methodology for estimating population density from
  point-centered quarter method (PCQM) surveys when distance measurements are truncated
  by a maximum search radius (right-censored). The package provides a unified framework
  for analyzing such incomplete data, addressing both completely randomly distributed
  (Poisson) and spatially aggregated (Negative Binomial) populations. Key features
  include: (1) Adjusted moment-based density estimators for censored distances; (2)
  Maximum likelihood estimation (MLE) of density under the Poisson (CSR) model; and
  (3) Simultaneous MLE of density and an aggregation parameter under the Negative
  Binomial model. For more details, see Huang, Shen, Xing, and Zhao (2026) <https://doi.org/10.48550/arXiv.2603.08276>.'
