teremos a palestra da nossa aluna de doutorado:

Izabel Nolau (PPGE-UFRJ)

*Título: *Model-based Inference for Rare and Clustered Populations from
Adaptive Cluster Sampling using Auxiliary Variables

*Resumo: *Rare populations, such as endangered animals and plants, drug
users and individuals with rare diseases, tend to cluster in regions.
Adaptive cluster sampling is generally applied to obtain information from
clustered and sparse populations since it increases survey effort in areas
where the individuals of interest are observed. This work aims to propose a
unit-level model which assumes that counts are related to auxiliary
variables, improving the sampling process, assigning different weights to
the cells, besides referring them spatially. The proposed model fits rare
and grouped populations, disposed over a regular grid, in a Bayesian
framework. The approach is compared to alternative methods using simulated
data and a real experiment in which adaptive samples were drawn from an
African Buffaloes population in a 24,108 square kilometers area of East
Africa. Simulation studies show that the model is efficient under several
settings, validating the methodology proposed in this paper for practical
situations.
