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?

Is ESDA need to be visually intrepreted or is there any quantitative measure for it? Is there any step wise procedure for performing kriging interpolation?

What is the real difference between Completely regularized spline, spline with tension and thin plate spline? How can we say that in RBF, the point Surface created must go through each measured sample value and also it predicts values above the maximum and below the minimum measured values

Thank you But if i want to any do any other kriging other than simple and disjunctive , can i assume the histogram data as normal as obtained in the word-Will there be any wrong with this? Is this assumption correct?

Thank You So Much While i did ESDA, with the temperature data , in the Histogram tool i observed that my data is not normally distributed and when i did transformations I couldnt find any change. Why is it like that? Was my data normally distributed? But it didnt show a bell shaped graph that appear for a normal distribution. I am attaching the screen shots of histogram and QQ plot result please check and help me

Thank you I would like to know whether there is any specific range for RBF interpolations? Because when i did my work, i obtained a default parameter as 30.262 for completely regularised spline, 43.588 for spline with tension and 1E20 for tension spline. Can i continue my work with these default parameters? Is this the right way? To find the best interpolation methods, is it the way that i change the parameters for one type of interpolation method and find the best model from it and again find best models for other methods by changing their corresponding parameters. For my work , is it necessary to create test data and training data and then do the analysis to get the best model?

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?
