Deriving formula between two ranges

**chetandb** · 10-31-2011, 05:21 AM

Hi All,

I have two ranges, for example,
X = {750.80, 5726.90, 7754.56} and Y = {696.91, 5713.06, 8015.54}.

I need to derive formula for Y, in terms of X as a baseline.
For example, Y = X + (n)X.

Can anyone tell me how to do this? How to find value of "n"?

Thanks and Regards
Chetan

If Y = X + (n)X.

then Y = X*(1 + n)

and Y/X = 1 + n

so n = Y/X - 1

And there are 3 values for each group. Do we need to take average of those?

I don't know if you need to take an average ... it's your data. What are you trying to do.

I thought you were trying to find the value of n for various pairs of values of X and Y.
