【Abstract】 This paper proposed a new computational method for obtaining the generalized inverse of the coefficient matrix of the normal equation, and a new algorithm for obtainning the best linear unbiased estimator and the confidenc interval of estimable function of parameter of a fixed linear model. With this new methodk the computations can be reduced remarkably.更多还原
