1. Line(F, E) → f
2. FitLineY({A, B, C, D}) → g
3. Polygon(K, A, G, O) → q1, k, a, g_1, o
4. Polygon(L, B, H, P) → q2, l, b, h, p
5. Polygon(M, C, I, Q) → q3, m, c, i, q
6. Polygon(N, D, J, R) → q4, n, d, j, r
7. TableText({"(x,y)", "observed y", "fitted y", "res"}, {A, y(A), y(K), y(A) - y(K)}, {B, y(B), y(L), y(B) - y(L)}, {C, y(C), y(M), y(C) - y(M)}, {D, y(D), y(N), y(D) - y(N)}, "c _") → text5
