A Framework for Mediation Analysis with Multiple Exposures, Multivariate Mediators, and Non-Linear Response Models
James P. Long, Ehsan Irajizad, James D. Doecke +2
Mediation analysis seeks to identify and quantify the paths by which an exposure affects an outcome. Intermediate variables which are effected by the exposure and which effect the…
A Flexible Procedure for Mixture Proportion Estimation in Positive-Unlabeled Learning
Zhenfeng Lin, James P. Long
Positive--unlabeled (PU) learning considers two samples, a positive set P with observations from only one class and an unlabeled set U with observations from two classes. The goal…
A Note on Parameter Estimation for Misspecified Regression Models with Heteroskedastic Errors
James P. Long
Misspecified models often provide useful information about the true data generating distribution. For example, if is a non-linear function of the least squares estimator $\…
A Study of Functional Depths
James P. Long, Jianhua Z. Huang
Functional depth is used for ranking functional observations from most outlying to most typical. The ranks produced by functional depth have been proposed as the basis for function…
Kernel Density Estimation with Berkson Error
James P. Long, Noureddine El Karoui, John A. Rice
Given a sample from , we construct kernel density estimators for , the convolution of with a known error density . This problem is known as d…
