Skill assessment of kriging

Hi,

I have a kriged GA layer of precipitation data from approximately 50 points (i.e. stations) and would like to assess the skill of the interpolated surface.

I would like to omit some of the stations prior to kriging, and calculate the mean absolute error between interpolated and actual data.Then repeat many times to give a distribution of errors.

Could anyone suggest an efficient method of carrying out the above task using the Geostatistical Wizard? For example, how can I remove some point data from the kriging without changing the source of the data?

Also, is the 'average standard error' equivalent to the 'mean absolute error'?

Thank you for your help, it is greatly appreciated.
