论文摘要
我们考虑了从非参数的角度来检测在两样本环境中稀疏异质混合物的问题，在非参数的角度来看，这种效果自身表现为积极的转变。我们建议进行两样本的更高批评测试，并表明它与所有稀疏性制度中广义的Guassian混合模型的一阶相当。
We consider the problem of detecting sparse heterogeneous mixtures in a two-sample setting from a nonparametric perspective, where the effect manifests itself as a positive shift. We suggest a two-sample higher criticism test, and show that it is first-order comparable to the likelihood ratio test for the generalized Guassian mixture models in all sparsity regimes.
