How can one fix the different parameters in the  geostatistical analyst tool for various interpolation techniques? such as power for IDW, Smoothening parameters for RBF, range ,sill and nugget for kriging.
Is there any range for these parameters? Should trend, transformations necessary to be considered?

Have you looked in the help?
http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00310000002p000000.htm

If you want additional information on splines I would suggest doing a literature search.

Respected sir,

Even though i read ESRI help regarding RBF functions: Completely regularized spline, spline with tension and thin plate spline- i couldnot make out the differences between the three.  Can you please help me with this ?  I read that all these provide similar output surfaces- then how can the user define these?
