Damping a least squares filter

Web2. Least squares fitting has the desirable property that if you have two different output values for the same input value, and you replace them with two copies of their mean, the least squares fit is unaffected. For example, the best fit line is the same for the following two sets of data: 0 1 0 5 1 5 2 6. and.
