In both equations, i is the index of all of the summations. These summations run for i = 1, 2, 3, and so on, up to n. Here n is the number of points you're fitting to the log curve.Hello,
I'm trying to follow Wolfram to do a least square fitting. There are multiple summations in the two equations to find the coefficients. Are the i's the same in this case?
No. The formula shown in the Wolfram page for the numerator of b is@Mark44
Sorry I just looked at it and got confused again. So for coefficient b, can I write the numerator as
