Los datos de garantía tratados estadísticamente son útiles para la predicción de reclamaciones futuras, para establecer comparaciones entre reclamaciones de productos y mejoras de ellos y estimación de la confiabilidad. Este análisis exige la disponibilidad de información diaria, que muchas veces sólo está disponible en forma agregada semanal o mensual debido a la logística de la empresa. En el presente trabajo se estudia el efecto que presenta la agregación de datos en los resultados del análisis.
Abstract: Warranty data, statistically well handled, is useful to predict future claims, to make comparisons between products claims, to estimate products field reliability, and to identify reliability improvements that can be made to the product. This analysis requires the availability of daily records that sometimes are only available in weekly or monthly total (grouped data) due to the nature of the operations of the organization. In this work the effect of the grouped data in the final results of the analysis is studied.
