Least Squares Fit to Non-polynomial Function

3. Least Squares Fit to Non-polynomial Function

The process is similar when fitting to a function that is not a polynomial. For instance, say that

W

xi	fi
.24	0.23
.65	-0.26
.95	-1.10
1.24	-0.45
1.73	0.27
2.01	0.10
2.23	-0.29
2.52	0.24
2.77	0.56
2.99	1.00

e wish to fit this function to the data shown at right. In this case, N = 10 and g = 3. The adjustable parameters are a, b and c.
