Inference for BART with Multinomial Outcomes

Yizhen Xu, Joseph W. Hogan, Michael J. Daniels +2

The multinomial probit Bayesian additive regression trees (MPBART) framework was proposed by Kindo et al. (KD), approximating the latent utilities in the multinomial probit (MNP) m…

Informed Pooled Testing with Quantitative Assays

Tao Liu, Joseph W Hogan, Wanning Su +3

Pooled testing is widely used for screening for viral or bacterial infections with low prevalence when individual testing is not cost-efficient. Pooled testing with qualitative ass…

Classification using Ensemble Learning under Weighted Misclassification Loss

Yizhen Xu, Tao Liu, Michael J. Daniels +3

Binary classification rules based on covariates typically depend on simple loss functions such as zero-one misclassification. Some cases may require more complex loss functions. Fo…
