Selecting sites to prove the concept of IAR4D in the Lake Kivu Pilot Learning Site

Farrow, Andrew; Opondo, Chris; Rao, KPC; Tenywa, Moses; … - In: African Journal of Agricultural and Resource Economics 08 (2013) 3

Selecting sites is an essential step in enabling the assessment of the impact of Integrated Agricultural Research for Development (IAR4D) in the Lake Kivu Pilot Learning Site. This paper reports on the process of identifying distinct administrative territories (sites) in which to establish...

Space-filling location selection

Michela, BIA; Philippe, VAN KERM - Luxembourg Institute of Socio-Economic Research … - 2013

This note describes a Stata implementation of a space-filling location selection algorithm. It optimally selects a subset from an array of locations so that the spatial coverage of the array by the selected subset is optimized according to a geometric criterion. Such an algorithm is useful in...

Assessing Performance of Leaf Area Index in a Monitored Mountain Ecosystem on Mount Elgon-Uganda

Oyana, Tonny; Kayendeke, Ellen; Adu-Prah, Samuel - In: International Journal of Applied Geospatial Research (IJAGR) 8 (2017) 1, pp. 64-80

This study investigated the performance of leaf area index (LAI) and photosynthetically active radiation (PAR) in a mountain ecosystem. The authors hypothesized that significant spatial and temporal differences exist in LAI and PAR values in the Manafwa catchment on Mt. Elgon. This was...

Finite population properties of predictors based on spatial patterns

Bruno, Francesca; Cocchi, Daniela; Vagheggini, Alessandro - Dipartimento di Scienze Statistiche "Paolo Fortunati", … - 2011

When statistical inference is used for spatial prediction, the model-based framework known as kriging is commonly used. The predictor for an unsampled element of a population is a weighted combination of sampled values, in which weights are obtained by estimating the spatial covariance function....

Space-filling location selection

Bia, Michela; Kerm, Philippe Van - In: Stata Journal 14 (2014) 3, pp. 605-622

In this article, we describe an implementation of a space-filling locationselection algorithm. The objective is to select a subset from a list of locations so that the spatial coverage of the locations by the selected subset is optimized according to a geometric criterion. Such an algorithm...
