DATA FITTING EXAMPLES

Consider the set of data:

x	f
1	0.5
2	2.5
3	2.0
4	4.0
5	3.5
6	6.0
7	5.5

Use one-dimensional arrays for the x and f data.

Fit a linear equation through the data using a least-squares regression. Compute the error using the second norm.

Answer: f = 0.07142857 + 0.8392857x with a second norm error of 2.998.
