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…

Inference in a generalized Bradley-Terry model for paired comparisons with covariates and a growing number of subjects

Ting Yan

Motivated by the home-field advantage in sports, we propose a generalized Bradley--Terry model that incorporates covariate information for paired comparisons. It has an -dimensi…

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…
