(Centro de Investigaciones en Matemática Pura y Aplicada (CIMPA) y Escuela de Matemática, San José, Costa Rica., 2021)
Capacidade de coleta de três métodos de amostragem e tamanho de amostra para lagartas e percevejos em soja
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2012-02-16)
This study aimed to compare the caterpillar and stinkbug collection capability of
sampling methods and to determine the sample size (number of sampling points) to estimate
the number of caterpillars and stinkbugs collected ...
The numbers of sample design for evaluation of the soil fertility
(UNIV ESTADUAL LONDRINA, 2011)
The determination of the amount of sample units that will compose the sample express the optimization of the workforce, and reduce errors inherent in the report of recommendation and evaluation of soil fertility. This study ...

(2011-01-01)
The determination of the amount of sample units that will compose the sample express the optimization of the workforce, and reduce errors inherent in the report of recommendation and evaluation of soil fertility. This study ...
The effective sample size for multivariate spatial processes with an application to soil contamination
(2021)
Effective sample size accounts for the equivalent number of independent observations contained in a sample of correlated data. This notion has been widely studied in the context of univariate spatial variables. In that ...
Amostragem de plantas em cafeeiro para avaliação do estado nutricional
(2015-01-01)
The foliar fertilization assists programs in order to obtain higher yields, however, it is essential to know the ideal number of plants to be sampled. The study aimed to determine in commercial coffee plantations, subjected ...
How Should Ecologists Define Sampling Effort? The Potential of Procrustes Analysis for Studying Variation in Community Composition
(2015-01-01)
Appropriate sampling effort is crucial for ecologists. Procrustes analysis can be used to tackle this question by quantifying the match between subsamples and the complete dataset. We used stream macroinvertebrates to show ...
Synthetic control charts with two-stage sampling for monitoring bivariate processes
(2007-01-01)
In this article, we consider the synthetic control chart with two-stage sampling (SyTS chart) to control bivariate processes. During the first stage, one item of the sample is inspected and two correlated quality characteristics ...
Occupancy Distributions Arising in Sampling from Gibbs-Poisson Abundance Models
(Springer, 2013)
Estimating the number n of unseen species from a k-sample displaying only p ≤ k
distinct sampled species has received attention for long. It requires a model of species abundance
together with a sampling model. We start ...
The Endothelial Sample Size Analysis in Corneal Specular Microscopy Clinical Examinations
(LIPPINCOTT WILLIAMS & WILKINSPHILADELPHIA, 2012)
Purpose: To evaluate endothelial cell sample size and statistical error in corneal specular microscopy (CSM) examinations. Methods: One hundred twenty examinations were conducted with 4 types of corneal specular microscopes: ...
