El análisis composicional del perfil de glucosa
J. Saperas Riera, J. A. Martín Fernández, J. Vehí Casellas
El Informe estandarizado de perfil de glucosa ambulatoria (AGP) ayuda a ver las tendencias de los valores de glucosa mediante gráficos. Un indicador del informe mide el porcentaje de tiempo diario que el paciente se encuentra dentro de unos rangos. Diariamente, se muestrea el % de lecturas del dispositivo que lleva conectado el paciente. En función de las lecturas obtenidas el paciente puede encontrarse dentro de una región objetivo o fuera. En el presente trabajo queremos analizar el indicador de porcentaje en tiempo desde una perspectiva composicional.
Las composiciones son vectores cuyos componentes representan partes de un todo. El espacio muestral de estos datos es el símplex, que tiene una estructura geométrica particular conocida como geometría de Aitchison. Definimos rigurosamente el concepto de conjunto convexo, función convexa y derivada composicional para asegurar que sean compatibles con la geometría del símplex i plantear un problema de optimización restringida.
Keywords: datos composicionales, geometría Aitchison, optimización restringida, convexidad, glucosa

Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport.
