In this article, we describe and apply the Fay-Herriot model with spatially correlated random area effects (Pratesi & Salvati, 2006) in order to predict the prevalence of anemia and childhood stunting in Peruvian districts. This prediction is based on data from the Demographic and Family Health Survey of the year 2019, which collects information about anemia and childhood stunting in children under the age of 12 years, as well as the National Census carried out in 2017. Our main objective is to produce reliable predictions for districts with sample sizes too small to provide accurate direct estimates, as well as for districts not included in the sample. The basic Fay-Herriot model (Fay & Herriot, 1979) addresses this issue by incorporating auxiliary information, typically available from administrative or census records. The Fay-Herriot model with spatially correlated random area ...

The dynamics of the unemployment rate over time reflects the performance of the labor market, one of the most important determinants of well-being in any economy. The unemployment rate is one of the main indicators used to analyze the prosperity and economic situation of a country, and also allows analyzing the economy from two perspectives: the first from the supply side and from the demand side. In this research we are going to analyze the dynamics of unemployment in Metropolitan Lima.For this purpose, we will use the data from the Permanent Employment Survey - EPE from 2002 to 2018 to calculate the monthly unemployment rates. We are interested in studying the development dynamics of the unemployment rate in Metropolitan Lima, and also in comparing the development dynamics ofthe said rate in different cones, men and women, and also the dynamics in different age groups. The main objecti...

En este artículo, obtenemos predicciones confiables del porcentaje de niños con anemia y el porcentaje de niños con retraso del crecimiento por distrito en el Perú, utilizando los datos de la Endes del año 2019 y del censo nacional realizado el año 2017, en los distritos donde el tamaño de la muestra no es suficiente para implementar una estimación directa, y en los distritos no muestreados. Como el objetivo principal de las encuestas nacionales es describir el estado de la población (por ejemplo, la salud, el estado de empleo y desempleo, gastos familiares, educación, etc.), uno de los problemas más comunes de las encuestas nacionales es que estas son generalmente planeadas de tal forma que tengan una buena representación solamente a nivel nacional, nacional urbano, nacional rural o región natural. Por tal motivo, la inferencia a niveles más desagregados, como a nivel dist...
