The research and its outcomes presented here focus on spatial sampling of agricultural resources. The authors introduce sampling designs and methods for producing accurate estimates of crop production for harvests across different regions and countries. With the help of real and simulated...

Il presente lavoro analizza la crescita di lungo periodo nell’area del Medio Oriente e Nord Africa, con l’obiettivo di verificare la presenza e la tipologia della convergenza nella regione durante il periodo 1950-2007. L’evidenza empirica del lavoro mostra che la vasta ed eterogenea area...

Small area estimators are often based on linear mixed models under the assumption that relationships among variables are stationary across the area of interest (Fay–Herriot models). This hypothesis is patently violated when the population is divided into heterogeneous latent subgroups. In this...

This paper proposes a local stationarity approach in EBLUP estimation with the aim to improve the reliability of relative poverty estimates in small areas. The results of the experimentations, performed in the framework of the European Statistics on Income and Living Conditions survey (EU-SILC),...

In sampling theory the large concentration of the population with respect to most surveyed variables constitutes a problem which is difficult to tackle by means of classical tools. One possible solution is given by cut-off sampling, which explicitly prescribes to discard part of the population;...
