Published in 2022 at "Human Brain Mapping"

DOI: 10.1002/hbm.25898

Abstract: In recent neuroimaging studies, threshold‐free cluster enhancement (TFCE) gained popularity as a sophisticated thresholding method for statistical inference. It was shown to feature higher sensitivity than the frequently used approach of controlling the cluster‐level family‐wise… read more here.

Published in 2022 at "Human Brain Mapping"

DOI: 10.1002/hbm.26029

Abstract: The dual‐process theory that two different systems of thought coexist in creative thinking has attracted considerable attention. In the field of creative thinking, divergent thinking (DT) is the ability to produce multiple solutions to open‐ended… read more here.

Published in 2022 at "Human Brain Mapping"

DOI: 10.1002/hbm.26177

Abstract: The literature of neuroimaging meta‐analysis has been thriving for over a decade. A majority of them were coordinate‐based meta‐analyses, particularly the activation likelihood estimation (ALE) approach. A meta‐evaluation of these meta‐analyses was performed to qualitatively… read more here.

Published in 2021 at "Statistics in medicine"

DOI: 10.1002/sim.9212

Abstract: Variable screening plays an important role in ultra-high-dimensional data analysis. Most of the previous analyses have focused on individual predictor screening using marginal correlation or other rank-based techniques. When predictors can be naturally grouped, the… read more here.

Published in 2022 at "Statistics in Medicine"

DOI: 10.1002/sim.9525

Abstract: Interference, the dependency of an individual's potential outcome on the exposure of other individuals, is a common occurrence in medicine and public health. Recently, targeted maximum likelihood estimation (TMLE) has been extended to settings of… read more here.

Published in 2020 at "Computational Economics"

DOI: 10.1007/s10614-020-10072-8

Abstract: We propose two Mathematical Programming with Equilibrium Constraints (MPEC) formulations: the MPEC-Sparse and the MPEC-Dense to estimate a class of separable matching models. We compare MPEC with the Nested Fixed-Point (NFXP) algorithm—a well-received method in… read more here.

Published in 2021 at "Computational Economics"

DOI: 10.1007/s10614-021-10139-0

Abstract: For Copula models, the likelihood function could be multi-modal, and some traditional optimization algorithms such as simulated annealing (SA) may get stuck in the local mode and introduce bias in parameter estimation. To address this… read more here.

Published in 2020 at "Extremes"

DOI: 10.1007/s10687-020-00379-y

Abstract: A common statistical problem in hydrology is the estimation of annual maximal river flow distributions and their quantiles, with the objective of evaluating flood protection systems. Typically, record lengths are short and estimators imprecise, so… read more here.

Published in 2020 at "Journal of Statistical Planning and Inference"

DOI: 10.1016/j.jspi.2019.06.008

Abstract: Abstract This paper investigates the quasi-maximum likelihood estimator (QMLE) of the structure-changed and two-regime threshold double autoregressive model. It is shown that both the estimated threshold and change-point are n -consistent, and they converge weakly… read more here.
