Instability of inverse probability weighting methods and a remedy for non-ignorable missing data
Pengfei Li, Jing Qin, Yukun Liu
Inverse probability weighting (IPW) methods are commonly used to analyze non-ignorable missing data under the assumption of a logistic model for the missingness probability. Howeve…
Testing Homogeneity in a heteroscedastic contaminated normal mixture
Xiaoqing Niu, Pengfei Li, Yuejiao Fu
Large-scale simultaneous hypothesis testing appears in many areas such as microarray studies, genome-wide association studies, brain imaging, disease mapping and astronomical surve…
Maximum likelihood abundance estimation from capture-recapture data when covariates are missing at random
Yang Liu, Yukun Liu, Pengfei Li +2
In capture-recapture experiments, individual covariates may be subject to missing, especially when the number of times of being captured is small. When the covariate information is…
Semiparametric empirical likelihood inference for abundance from one-inflated capture-recapture data
Yang Liu, Pengfei Li, Yukun Liu +1
Abundance estimation from capture-recapture data is of great importance in many disciplines. Analysis of capture-recapture data is often complicated by the existence of one-inflati…
