probability of approximation
 

I have a trendline on the chart and Value of probability of approximation
(R^2) correspondent to this trendline.
How can I return this value in a sell as number?
I appreciate your help.

Use the RSQ worksheet function.

R^2 is usually called "coefficient of determination" in statistics. It's the
proportion of variation in Y that is explained by X in the model. I have
never heard it described as the "probability of approximation."

Or, if it is more than a linear trendline, use LINEST with the
statistics flag set.

Mike-
Thanks a lot. "probability of approximation." is my erroneous translation
from Russian- I use Russian localization of MS Excel. It suppose to be (in
direct translation) - " reliability of approximation".
But of course "coefficient of determination" is correct.

PS Jerry, thanks a lot, as well.
