Composite Likelihood Methods Based on Minimum Density Power Divergence Estimator

Entropy, 2017
In this paper, a robust version of the Wald test statistic for composite likelihood is considered by using the composite minimum density power divergence estimator instead of the composite maximum likelihood estimator.

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.

Omnibus Tests for Multiple Binomial Proportions via Doubly Sampled Framework with Under-Reported Data

Stats, 2022
Previously, Rahardja (2020) paper (in the first reference list) developed a (pairwise) multiple comparison procedure (MCP) to determine which (proportions) pairs of Multiple Binomial Proportions (with under-reported data), the significant differences ...

Empirical likelihood inference and goodness-of-fit test for logistic regression model under two-phase case-control sampling

Statistical Theory and Related Fields, 2022
Due to cost-effectiveness and high efficiency, two-phase case-control sampling has been widely used in epidemiology studies. We develop a semi-parametric empirical likelihood approach to two-phase case-control data under the logistic regression model. We

Strategies for the diagnosis and treatment of the iliac vein compression syndrome

Journal of Interventional Medicine, 2019
Aim: To evaluate the diagnosis and treatment strategies for the iliac vein compression syndrome (IVCS) and the factors that affect the treatment outcome. Methods: In total, 69 patients with IVCS were enrolled in the study. The patients underwent computed

Three influential design quantities on the power of Wald-type tests for treatment comparisons in clinical trials

Journal of Statistical Research, 2023
In clinical trials, efficient statistical inference is critical to the well-being of future patients. We therefore construct Wald-type tests for the hypothesis of treatment-by-covariate interaction when treatments are assigned to patients by an adaptive design and the true model is a generalized linear model. Our measure of efficiency is the power of the

Garch Model Test Using High-Frequency Data

Mathematics, 2020
This work is devoted to the study of the parameter test for the Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model. Based on the daily GARCH model, using the parameter estimator obtained by intraday high-frequency data, the adjusted ...
