I have 20 points in the form of x and y.
And i am asked to
Assume that there may be the following functional relationships:y= w0 + w1*x, or y = w0 + w1*(x^2)
Perform least squares regression for both and determine what thebest
functional form is.
(Hint: use the first half of the data as training set and the second half
as test set.)
What am i meant to do, i have no idea where to begin.
