Correcting negative kriging weight in krigeST

Sojin Lee
Dear R-sig-Geo users,

I'm currently using krigeST for 3-d geostationaly sattlite data
interpolation, and I'm trying to estimate "Interpolation variance" in
Yamamoto et al, 2000.

My problem is that the variance is somtimes negative. I'm thinking
that it is due to the negative kriging weights. I found that there is
a solution in Deutsch (1995)

But I'm not sure there is already a option in krigeST fuction. Could
you let me know about the solution?

Thank you for your consideration.

Best regards,
