Log-F-penalized Conditional Logistic Regression for Sparse Data
Ying Yu, Jiying Wen, Jinko Graham +1
We investigate penalized likelihood methods for estimation and inference in conditional logistic regression. The standard conditional maximum likelihood estimator is known to be bi…

JinCheol Choi, Donghuan Lu, Mirza Faisal Beg +2
Alzheimer's disease (AD) is a chronic neurodegenerative disease that causes memory loss and decline in cognitive abilities. AD is the sixth leading cause of death in the United Sta…
Simple Measures of Individual Cluster-Membership Certainty for Hard Partitional Clustering
Dongmeng Liu, Jinko Graham
We propose two probability-like measures of individual cluster-membership certainty which can be applied to a hard partition of the sample such as that obtained from the Partitioni…
A Bayesian Group Sparse Multi-Task Regression Model for Imaging Genetics
Keelin Greenlaw, Elena Szefer, Jinko Graham +2
Motivation: Recent advances in technology for brain imaging and high-throughput genotyping have motivated studies examining the influence of genetic variation on brain structure. W…
