摘要：

In a detailed study of the accuracy of the Cholesky method for solving least squares equations, points in the algorithm at which accuracy is lost are identified, methods for improving accuracy are discussed, and simple formulas for predicting accuracy from the maximum variance inflation factor (as well as from the condition number) are evaluated. The central role of cancellation in determining accuracy is emphasized. © 1990.
