Empirical likelihood on the full parameter space

, 2013
We extend the empirical likelihood of Owen [Ann. Statist. 18 (1990) 90-120] by partitioning its domain into the collection of its contours and mapping the contours through a continuous sequence of similarity transformations onto the full parameter space.

A Euclidean likelihood estimator for bivariate tail dependence [PDF]

, 2012
The spectral measure plays a key role in the statistical modeling of multivariate extremes. Estimation of the spectral measure is a complex issue, given the need to obey a certain moment condition.

Adjusted empirical likelihood analysis of restricted mean survival time for length-biased data [PDF]

Journal of Mahani Mathematical Research
The Restricted Mean Survival Time (RMST) serves as a valuable and extensively utilized metric in clinical trials. However, its application becomes intricate when dealing with data affected by length-biased sampling, rendering traditional inference ...

Regenerative block empirical likelihood for Markov chains

, 2011
Empirical likelihood is a powerful semi-parametric method increasingly investigated in the literature. However, most authors essentially focus on an i.i.d. setting.

Joint Statistical Inference for the Area under the ROC Curve and Youden Index under a Density Ratio Model

Mathematics
The receiver operating characteristic (ROC) curve is a valuable statistical tool in medical research. It assesses a biomarker’s ability to distinguish between diseased and healthy individuals.

Empirical and Simulated Adjustments of Composite Likelihood Ratio Statistics [PDF]

, 2013
Composite likelihood inference has gained much popularity thanks to its computational manageability and its theoretical properties. Unfortunately, performing composite likelihood ratio tests is inconvenient because of their awkward asymptotic ...

Likelihood-based random-effects meta-analysis with few studies: empirical and simulation studies [PDF]

BMC Medical Research Methodology, 2018
BackgroundStandard random-effects meta-analysis methods perform poorly when applied to few studies only. Such settings however are commonly encountered in practice.

Patient‐Level Barriers and Facilitators to Inpatient Physical Therapy in Adolescents and Young Adults With a Hematological Malignancy: A Qualitative Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite their increased risk for functional impairment resulting from cancer and its treatments, few adolescents and young adults (AYAs) with a hematological malignancy receive the recommended or therapeutic dose of exercise per week during inpatient hospitalizations.

Weighted Graph-Based Two-Sample Test via Empirical Likelihood

Mathematics
In network data analysis, one of the important problems is determining if two collections of networks are drawn from the same distribution. This problem can be modeled in the framework of two-sample hypothesis testing.
