Web3.2.2.2 OLS - System of Partial Derivatives Method. Suppose that we choose ˆβ0 and ˆβ1 to minimize the sum of squared residuals : RSS = N ∑ i = 1ˆϵ2 i = N ∑ i = 1(Yi − ˆβ0 − ˆβ1Xi)2. The term Ordinary Least Squares (OLS) comes from the fact that these estimates minimize the sum of squared residuals. WebIt is a property of OLS that the residuals must sum to zero if there is a constant or the equivalent in the model, but all of the data points are above the regression fit except one, which is only slightly below, in the first two figures. This is mathematically impossible.
