I can understand the relation between Bochner's theorem and PD function. But could not properly understand and connect all three elements namely, Kriging, Bochner's theorem and PD function. I would love to know a clear connection between these three. May be these three are related through Fourier transform, my wild guess; any clarification would be appreciated.
