where \(N\) is the size of \(s\) and \(\lambda\) is the array of weights. This is what we want to calculate from a fitted variogram model. Assumed that \(\lambda\) had already been calculated, estimating the prediction is pretty straightforward:

The scipy.interpolate packages wraps the netlib FITPACK routines (Dierckx) for calculating smoothing splines for various kinds of data and geometries. Although the data is evenly spaced in this example, it need not be so to use this routine.
