Resumo

Este artigo apresenta procedimentos inferenciais para construir intervalos de confiança em índices de capacidade Cp e Cpk através de técnicas de reamostragem (bootstrap) quando os dados provenientes de processos normais são autocorrelacionados.

Palavras-chave

Autocorrelação, bootstrap, índices de capacidade Cp e Cpk, séries temporais

Abstract

This paper presents procedures to build confidence intervals for capability indices Cp and Cpk based on bootstrap (resampling) methodology when data from the normal process are autocorrelated.

Keywords
