I am trying to perform an ordinary kriging interpolation using the geostatistical wizard.  I have a very large dataset (approximately 5000 points) that covers about 12,000 square meters.  I would like to change the length of the major and minor axes but they are grey'd out - like that option is unavailable.  Can anyone tell me why I don't have this option?  Any suggestions will be much appreciated.
