Casio FC200V, FC200VSIH y –, – 4C, – 4C, – B +, A – y, – B –, A – y, y = Σx, n = A + Bx + Cx2, Sxx = Σx2– (Σx)2 n, Sxy = Σxy – (Σx.Σy) n, Sxx2 = Σx3 – (Σx.Σx2) n

Calculation formula used for each command

A = Σny – B(Σnx ) – C(Σnx2 ) Sxy.Sx2x2 – Sx2y.Sxx2

B = Sxx.Sx2x2 – (Sxx2)2 Sx2y.Sxx – Sxy.Sxx2 C = Sxx.Sx2x2 – (Sxx2)2Sxx = Σx2– (Σx)2 nSxy = Σxy – (Σx.Σy) nSxx2 = Σx3 – (Σx.Σx2) n
