Abstract
Este documento propone una carta de control CUSUM multivariada espacial para monitorear la media de una sola caracteristica de un producto o proceso, cuando las mediciones se toman en diferentes ubicaciones en cada elemento muestreado. Para estimar la matriz de varianza y covarianza, se utilizan algunas herramientas de la geoestadistica, teniendo en cuenta la correlacion espacial entre las mediciones. El desempeno de esta carta de control se explora por simulacion y su uso se ilustra con un ejemplo.
期刊介绍：
The Colombian Journal of Statistics publishes original articles of theoretical, methodological and educational kind in any branch of Statistics. Purely theoretical papers should include illustration of the techniques presented with real data or at least simulation experiments in order to verify the usefulness of the contents presented. Informative articles of high quality methodologies or statistical techniques applied in different fields of knowledge are also considered. Only articles in English language are considered for publication.
The Editorial Committee assumes that the works submitted for evaluation
have not been previously published and are not being given simultaneously for publication elsewhere, and will not be without prior consent of the Committee, unless, as a result of the assessment, decides not publish in the journal. It is further assumed that when the authors deliver a document for publication in the Colombian Journal of Statistics, they know the above conditions and agree with them.
