• Fortran IV trent-surface program for the IBM 360 model 40 computer

      Heiner, Lawrence; Geller, Stephen P. (University of Alaska Mineral Industry Research Laboratory, 1966)
      A Fortran IV trend surface program with polynomial contouring and residual plotting has been adapted to the University of Alaska IBM 360 Model 40 Computer. The program will compute equations of polynomials of the first through sixth degree, measures of the goodness of fit of the surfaces, tabulate original data, x y coordinates and corresponding residuals for each surface; contour each polynomial, and plot original values and residuals for each surface computed.
