| contents | Comparison of Process Capability Indices under Autocorrelated Data Rubén Darío Guevara José Alberto Vargas Física, Astronomía y Matemáticas SPC Estimation Autocorrelation Process analysis Process capability indices The process capability indices provide a measure of how a process fitswithin the specification limits. In calculating indices is usual to assume thatthe process data are independent. However, in industrial applications dataare often autocorrelated. This paper deals with the indices Cp, Cpk, Cpm andCpmk when data are autocorrelated. Variances for their estimators are derivedand coverage probabilities of some confidence intervals are calculated. 2007 artículo científico 0120-1751 https://www.redalyc.org/articulo.oa?id=89930210 en http://www.redalyc.org/revista.oa?id=899 Revista Colombiana de Estadística application/pdf Universidad Nacional de Colombia Revista Colombiana de Estadística (Colombia) Num.2 Vol.30 |
