我想查看译文中含有：的双语例句  sufficient statistics
 Rotation testing handles this problem by conditioning on sufficient statistics. The paper proposes a model based approach to this problem by utilizing the information contained in the sufficient statistics obtained from fitting a model to the public data by conditioning on the survey data. Optimal batch-sequential designs are difficult to compute, even when sufficient statistics and relatively uncomplicated loss functions simplify the calculations required. To accommodate the spatial constraints in this domain, we compute virtual measurements as sufficient statistics to be used in the M-step. We then determine the data summaries (sufficient statistics) for these parameters. 更多 The paper introduces the sequential algorithm for joint detection and estimation on the basis of sufficient statistics and reproducing probability density function.
