Least square method solved example pdf. Simple linear regression : (xi, yi) ∈ R2 y −→ find θ1, θ2 such that the data fits the model y = θ1 + θ2x How does one measure the fit/misfit ? Least squares method The least squares method measures the fit with the Sum of Squared Residuals (SSR) n X S(θ) = (yi − fθ(xi))2, Steps in Least-Squares Data Fitting 1. Recent variations of the least square method are alternating least squares (ALS) and partial least squares (PLS). 2. 5. Note: If you want to solve a least squares problem by hand with pencil and paper, it is usually easier to use the normal equations. Select a function type (linear, quadratic, etc. 3 Solution of Rank Deficient Least Squares Problems If rank(A) < n (which is possible even if m < n, i.
