Dear Experts,
I would request you to build a macro to compute the coefficent of determination, from a fitting power function, to the data..

data are in row-wise fashion......

1 2 4 3 5 6 2 4 5 7
2 3 4 1 4 6 3 1
1 2 4 3 5 6 2 4 5 4 5 8

1st half of the row are the X- and 2nd half is the Y-
I want to fit X-Y data with power function and corresponding best fitting index (COD) or called R2, I want to estimate..

I have thousands of rows like this........

kindly help me...

regards
N
