Alright Bill, I ended up using your explanation found here: http://forums.esri.com/thread.asp?c=93&f=1740&t=288054 It worked wonderfully, but when I received the output correlation grid, it had a high of 81 and a low of -81. I know I saw another member on the forum have a similar situation arise and I can't quite seem to find the thread that the solution to their problem was located. Can you help? I'll keep searching though in the meantime. Thanks again, Seth

Thank you Bill! That is what I was referring to, I just could not think of the name or where I had seen something similar. I will try out your suggestion and see what I can come up with! Thanks for the help again, Seth

Hi all, I have a question about calculating the correlation between two grids. I am aware how to get a single correltation value as an overall correltaion value, but is there a way to produce a resulting grid with a correlation value for each cell? I would like to have a visual aid for the correlation between the two variables over the entire study site ultimately. I know the two attributes are closely correlated (using Spearman correlation), I just want to see over which areas the correlations are highest. Thanks for any help, Seth

Thank you so much for the help Steve! So in order to obtain the true values in the grid conversion, it would appear that I would need to select a cell size of less than one, is this correct? Processing time is not an issue, but I would rather the program not crash when performing the large amount of calculations needed.

Hi all, I have a bizarre issue occurring when I try and convert my resulting image into a raster for analysis. The conversion is successfull, but the max and min values are terribly off. In my Cokriging image, the min is zero and the max is around 420. When the image is converted to a raster with a cell size of one, the min is slightly above one and the max is around 130. Does anyone have any idea why it is ommitting a large portion of the values? Thank you for any help, Seth
