GEOSTATS: Sparse matrix solvers and kriging
- See Barry, Ronald, and R. Kelley Pace, "Kriging with Large Data Sets Using Sparse Matrix Techniques," Communications in Statistics: Computation and Simulation, Volume 26, Number 2, 1997, p. 619-629.
We used Matlab. There are a number of sparse matrix routines in C and Fortran which one could employ. If you do not wish to conduct maximum likelihood (i.e., don't need determinants), one could also employ iterative sparse techniques.
