摘要
Abstract
Aimed at the disadvantages in data snooping algorithm to find observation gross errors,the calculation process about model data snooping is detailed. Sequential detection of gross error, a new scheme based on the reduction principle of predecessor' s research, was developed to reduce the calculation amount of the gross error detection. By using the block matrices it gets the fast calculation for the inverse matrix of covariance matrix. Meanwhile,the results indicate that it greatly improve the efficiency of gross error snooping.关键词
