WebMultivariate interpolation modeling, today known as cokriging, was first used to improve prediction of the earth’s gravitational field using data from wind measurements made by Lev Gandin in 1963. Cokriging models are efficient, but they require certain restricting assumptions, in particular, assumptions about data normality and stationarity.

Web1.2 Lagrange-Hermite interpolation So far we looked for a graph passing through d+1 given points. It is very natural (and often necessary) to control the local geometry of the graph near the interpolation points. This amounts to impose conditions on the derivatives of the polynomial at the interpolation points and thus leads to the concept of
