Physical or geographic location proves to be an important feature in many data science models, because diverse natural and social phenomenon have a spatial component. Spatial autocorrelation measures the extent which locally adjacent observations of same are correlated. Although statistics like Moran’s I Geary’s C widely used measure autocorrelation, they slow: All popular methods run $$\Omega ...

•An improved YASSO model is proposed by considering residual spatial autocorrelation.•Model prediction errors are minimised using GIS data at the appropriate spatial scale.•Topographical factors describe 24-49% of variation in soil carbon.

By buying cheap and selling dear, risk-neutral commodity speculators can smooth commodity prices and induce serial dependence in price even when none would exist under a simple process of supply and demand. Commodity prices are variable and strongly positively correlated from one year to the next. The variability is often explained by supply factors, and the autocorrelation by the activities of...

Warp and weft spacing and its coefficient of variation affect the physical properties of fabrics such as fabric hand, frictional and mechanical properties. In this paper the weft and warp spacing and its coefficient of variation for plain weave is calculated using Fourier transforms. Different methods have been used in this work including autocorrelation function. First, two dimensional power s...

The causes of the recent re-emergence of malaria in the East African highlands probably involve a complex interplay among multiple factors, including climate, land use, topography, inadequate use of antimalarial drugs and drug resistance, socioeconomic status, health policy and public health control measures. It is important to determine the relative contribution of these factors. In our study,...
