- Profile Monitoring for Compositional Data Rubén Darío Guevara-González José Alberto Vargas-Navas Dorian Luis Linero-Segrera Física, Astronomía y Matemáticas Control chart Dirichlet distribution Statistical process control In a growing number of quality control applications, the quality of a product or process is best characterized and summarized by a functional relationship between a response variable and one or more explanatory variables. Profile monitoring is used to understand and to check the stability of this relationship over time. In some applications with compositional data, the relationship can be characterized by a Dirichlet regression model. We evaluate five T2 control charts for monitoring these profiles in Phase I. A real example from production of concrete is given. 2014 artículo científico 0120-1751 https://www.redalyc.org/articulo.oa?id=89931327011 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.1 Vol.37
