Hi folks, I am working on an exercise which compares the performance of different Kriging methods including ordinary Kriging, Co-Kriging and Universal Kriging. Regarding Co-Kriging, I am trying to conduct Co-Kriging using two secondary variables separately. RMSEs from these two Co-Kriging are smaller than those from Ordinary Kriging. I am also conducting Co-Kriging using both secondary variables. However, RMSEs are larger than those from Co-Kriging with either secondary variable separately. I am wondering if these results do make sense since I expect that RMSEs from Co-Kriging using both variables are smaller. Any comments are welcome.
Thanks, Kai __________________________________________________ 赶快注册雅虎超大容量免费邮箱? _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
