Please explain a little better what you are trying to do.

For example, do you have a table of values of x and y, and are you trying to interpolate to find an intermediate value? Or are you trying to use regression or some other technique to forecast the y value corresponding to the next x value?

And are you looking to perform statistical tests, or are you looking for a non-mathematical answer?
