Manual Calculation of Average Standard Error for IDW

Hello,

I have a data set of about 500 points with depth values. Literature suggests that IDW and kriging are best for bathymetry and so I'm doing a comparison between different models to determine the "best fit" one. As best I understand it, the Geostatistical Analyst does not compute the Average Standard Error, Root-mean-square Standardized, and Mean Standardized errors for IDW because IDW does not include a semivariogram in the modeling process. My question is, is there any way to calculate these errors by hand for an IDW prediction surface?

Thanks!
Jenni
