no code implementations NeurIPS 2012 Chunxiao Zhou, Jiseong Park, Yun Fu

In this paper, a novel, computationally fast, and alternative algorithm for com- puting weighted v-statistics in resampling both univariate and multivariate data is proposed.

Efficient Moments-based Permutation Tests

no code implementations NeurIPS 2009 Chunxiao Zhou, Huixia J. Wang, Yongmei M. Wang

In this paper, we develop an efficient moments-based permutation test approach to improve the system’s efficiency by approximating the permutation distribution of the test statistic with Pearson distribution series.
