Kriging input with uncertainties

I have a data set that I'd like to interpolate using Kriging. I know that ArcGIS can generate a variance raster alongside the interpolation result that shows the likely variance from the interpolation.

However, the z values in my input data have uncertainties of their own. Is there a way to have these uncertainties reflected in the output of the Kriging process? In other words, can the output variance raster express the variance that takes into account the uncertainty of the input data?

Cheers,
Steve.

Perfect!

The process ended in an error so I lowered the number of simulations to 50

and it worked fine. I'll slowly bump up the number of realizations to

figure out what my clunky, old work computer can handle. I think it's my

computer, not the number of points I have (I only have 160 sites across the

contiguous U.S.).

Thanks again for you help. I could not have done this without your

thoughtful and detailed responses!

I have a similar question, but slightly different. I want to incorporate a bounding range of possible outputs in the interpolation per point. In other words, each point used in the kriging interpolation has a value and an acceptable range for modeled output in the interpolation. Can this be done?
