Hi, everyone.

I need to fit a set of data with an approximating function. I have tried functions such as polynomial, exponential & power law, but without success.

Pls., could someone kindly help fit the set of data given below with a closely approximating curve, and give the approximating function.

I need to use the approximating function for further analysis.

Data:

i 1 2 3 4 5 6 7 8 9 10 11 12 13 x 0.161166 0.53935

0.844731

0.910587

0.98339
