Regression models of DRS software

y = a0 + a1 x1k1 + a2 x1k2

Formula in:     y   -  is objective function

x -  is  variable

Get the coefficient through the use of “DRS”, and get coefficient, power and test parameter as follows

 Result Verification Parameters a0 = -.661582500004011 Correlation coefficient(R):0.999614113978291 a1 = 1.08247715469953 Statistical variable(F):10359.2733755249 a2 = -5.30251329687443E-13 Residue standard deviation(S):0.25668560536189 k1 = .82 Biggest error:0.1110527357773081982509 k2 = 6.969999999999 Equal error:6.850973E-02 Equal relating error:0.0115132767485429297150007794
