Web22 okt. 2004 · We formally investigate the spatial variation by using an empirical variogram of the data. We first remove the temporal trends by taking the first differences for each time series from the 15 sites, i.e. we obtain, w(s i,t) = z(s i,t + 1)−z(s i,t) for t = 1,…,T−1 and i = 1,…,n.The time series plots of the difference data (not shown) confirmed that there were … WebCo-Kriging. Co-kriging (CK) is an extension of ordinary kriging in which additional observed variables (know as co-variate which are often correlated with the variable of interest) are used to improve the precision of the interpolation of the variable of interest. Unlike regression and universal kriging, Co-Kriging does not require that the ... oudtshoorn agri

WebKriging is an interpolating model that is a linear combination of a known function f i ( x) which is added to a realization of a stochastic process Z ( x) y ^ = ∑ i = 1 k β i f i ( x) + Z ( x). Z ( x) is a realization of a stochastic process with mean zero and spatial covariance function given by. c o v [ Z ( x ( i)), Z ( x ( j))] = σ 2 R ...
