Corrigenda: The Numerical Reliability of Econometric Software
本文是对1999年一篇关于计量经济软件数值可靠性论文的勘误，修正了第647页左栏上方的方程印刷错误，涉及回归方程和正规方程的计算。
CORRIGENDA Volume 37, June 1999 In "The Numerical Reliability of Econometric Software", by B. D. McCullough and H. D. Vinod, there are misprints in some equations on page 647 in the upper part of the left-hand column. The passage should read as follows: The normal equations are 6?^ + 61.5? ^ = 7.261 61.5?^ + 630.55? ^ = 74.5053 which yields a regression line of Y^ = ?3.478 + 0.457X. Suppose that the normal equations had been computed only to four significant digits as 6?^ + 61.5? ^ = 7.261 61.5?^ + 630.6? ^ = 74.50.
