Robust-BD Estimation and Inference for General Partially Linear Models
Entropy, 2017 The classical quadratic loss for the partially linear model (PLM) and the likelihood function for the generalized PLM are not resistant to outliers. This inspires us to propose a class of “robust-Bregman divergence (BD)” estimators of both the parametric

Modified score statistic based on bias reduction [PDF]
, 2023 openLikelihood inference provides a valuable and general inferential framework for several statistical models, especially parametric ones. However, in some settings maximum likelihood estimators may be affected by a non-negligible presence of bias ...

On the Distribution of Wald's Classification Statistic
The Annals of Mathematical Statistics, 1951 In this paper we shall consider the exact distribution of Wald's classification statistic $V$ in the univariate case, some theoretical approximations in various multivariate cases, and an empirical distribution in a particular multivariate case. We shall also draw some conclusions as to the potential usefulness of the statistic $V$ and the work which ...

Robustness Property of Robust-BD Wald-Type Test for Varying-Dimensional General Linear Models
Entropy, 2018 An important issue for robust inference is to examine the stability of the asymptotic level and power of the test statistic in the presence of contaminated data.

Molecular Oncology, EarlyView.CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting

Homogeneity Test for Multiple Semicontinuous Data with the Density Ratio Model
Mathematics, 2023 The density ratio model has been widely used in many research fields. To test the homogeneity of the model, the empirical likelihood ratio test (ELRT) has been shown to be valid. In this paper, we conduct a parametric test procedure.
