If the chosen set is inadequate, the least-squares procedure will show a poor fitness (the interpolation errors are large compared with [tau]), and the set can then be extended.
involving six samples; by this kernel, the interpolation error has a fourth-order convergence rate.
Interpolation error m was calculated using following formula:
2] (t) are uncorrelated by construction, we can make use of the Pythagorean theorem to express the interpolation error at [[sigma].
To reduce interpolation error further, the climatologically aided interpolation can be combined with topographically informed interpolation, because CAT and TII procedures explain correlated but somewhat different components of the total spatial variance (Willmott and Matsuura, 1995).
After the CFA interpolation coefficients are preliminarily estimated, an interpolation error, which computed by a weighted sum of errors of nine pixels categories, is obtained to evaluate the veracity of the estimation.
At high frequencies, grids are widely spaced and the interpolation error is large.
