Abstract
Objetivou-se, neste trabalho, avaliar intervalos de confiança de diferentes funções lineares compostas por proporções binomiais construídas com base no método de Wald e Wald ajustado utilizando a técnica de bootstrap infinito. Considerados diversos tamanhos amostrais (n is), parâmetros (p) e número de coeficientes das funções lineares. Concluiu-se, por meio das probabilidades de cobertura dos intervalos de confiança das populações binomiais, cujas proporções foram baixas (p=0,2) e considerando diferentes tamanhos de amostras, que a generalização bootstrap do método de Wald ajustado foi eficiente para funções lineares cujos coeficientes indicaram a comparação de uma proporção versus as demais.
This work aimed to evaluate confidence intervals of different linear functions of binomial proportions base on Wald and Wald's adjusted method using the infinity bootstrap technique. Several sample sizes (n i), binomial parameters (p) and number of coefficients of the linear functions were considered. One concluded through the probabilities of binomial population confidence covered intervals that the bootstrap generalization of adjusted Wald's method was efficient for linear functions whose coefficients indicated a comparison of versus the others proportion (p=0.2) considering different sample sizes.
