A GENERALIZED LEAST SQUARES PROGRAM FOR THE IBM 7090 COMPUTER
M. H. Lietzke · 1962
A generalized least squares program was written for the IBM 7090 computer. The program includes a subroutine to perform all matrix operations and furnish the calling program with the coefficients, standard errors in the coefficients, variance of fit, and a complete error analysis; and a calling program which reads input, calls the subroutine, and writes requested output. The subroutine may be used separately in any Fortran or FAP program where a least squares fit is needed. The user must furnish a subroutine to define the desired function and partial derivatives with respect to the coefficients. (auth)
