Hi All,

I am trying find an equation for a set of data. Please send in ur inputs.

I tried fourier series, tried fitting a sine curve, but i had poor R2.

R2 should be near 0.99. Data is as follows:

This is very scatered data and i don't think that you can find any function thatcan give you an R^2 of 0.99.
Still if you want you can try www.curvefit.com
