WebJul 30, 2024 · A geometric interpretation of linear regression is, perhaps, more intuitive. The column vectors of X span a subspace, and minimizing the residuals amounts to making an orthogonal projection of y onto this subspace, as seen in the figure below. By orthogonality, the normal equations are immediately obtained. ... WebRewriting the equation in this way helps in a geometric interpretation (see Figure 4.4). 2 The stepped curve is the cumulative arrival process A(t); each packet arrival causes the cumulative arrivals to increase by the packet length.For any t, we obtain X(t) by considering, for each s ≤ t, straight lines with equations A(s) + C·(t–s).The value of X(t) is the … WebSep 16, 2024 · Interpretation of Linear Regression.
