Abstract :Several methods have been developed to estimate the regression model parameters using the Least Absolute Values method. In this study, three methods for finding Least Absolute Values Estimates developed by Charnes et al. insert ignore into journalissuearticles values(1995);, Gonin and Money insert ignore into journalissuearticles values(1989); and Li insert ignore into journalissuearticles values(1998);, are compared with respect to Central Process Unit insert ignore into journalissuearticles values(CPU); time and the size of the determination coefficients.
Keywords : Least Squares, Least Absolute Values, Linear Programming, Determination Coefficients, CPU Time
