Inference in the model for directed networks under local differential privacy
Xueying Sun, Ting Yan, Binyan Jiang
We explore the edge-flipping mechanism, a type of input perturbation, to release the directed graph under edge-local differential privacy. By using the noisy bi-degree sequence fro…
Testing degree heterogeneity in directed networks
Lu Pan, Qiuping Wang, Ting Yan
In this study, we focus on the likelihood ratio tests in the model for testing degree heterogeneity in directed networks, which is an exponential family distribution on direc…
Moment estimation in paired comparison models with a growing number of subjects
Qiuping Wang, Lu Pan, Ting Yan
When the number of subjects, , is large, paired comparisons are often sparse. Here, we study statistical inference in a class of paired comparison models parameterized by a set…
Likelihood ratio tests in random graph models with increasing dimensions
Ting Yan, Yuanzhang Li, Jinfeng Xu +2
We explore the Wilks phenomena in two random graph models: the -model and the Bradley-Terry model. For two increasing dimensional null hypotheses, including a specified null $H…
