Estimation of heterogeneous principal effects under principal ignorability
Rui Zhang, Charles R. Doss, Jared D. Huling
We study estimation and inference for heterogeneous principal causal effects with binary treatments and binary intermediate variables. Principal causal effects are subgroup effects…
A nonparametric doubly robust test for a continuous treatment effect
Charles R. Doss, Guangwei Weng, Lan Wang +2
The vast majority of literature on evaluating the significance of a treatment effect based on observational data has been confined to discrete treatments. These methods are not app…
Unlinked monotone regression
Fadoua Balabdaoui, Charles R. Doss, Cécile Durot
We consider so-called univariate unlinked (sometimes ``decoupled,'' or ``shuffled'') regression when the unknown regression curve is monotone. In standard monotone regression, one…
An explicit mean-covariance parameterization for multivariate response linear regression
Aaron J. Molstad, Guangwei Weng, Charles R. Doss +1
We develop a new method to fit the multivariate response linear regression model that exploits a parametric link between the regression coefficient matrix and the error covariance…
Bandwidth selection for kernel density estimators of multivariate level sets and highest density regions
Charles R. Doss, Guangwei Weng
We consider bandwidth matrix selection for kernel density estimators (KDEs) of density level sets in , . We also consider estimation of highest density regio…
Concave regression: value-constrained estimation and likelihood ratio-based inference
Charles R. Doss
We propose a likelihood ratio statistic for forming hypothesis tests and confidence intervals for a nonparametrically estimated univariate regression function, based on the shape r…
Univariate log-concave density estimation with symmetry or modal constraints
Charles R. Doss, Jon A. Wellner
We study nonparametric maximum likelihood estimation of a log-concave density function which is known to satisfy further constraints, where either (a) the mode of i…
Bracketing numbers of convex and -monotone functions on polytopes
Charles R. Doss
We study bracketing covering numbers for spaces of bounded convex functions in the norms. Bracketing numbers are crucial quantities for understanding asymptotic behavior for…
Inference for a Two-Component Mixture of Symmetric Distributions under Log-Concavity
Fadoua Balabdaoui, Charles R. Doss
In this article, we revisit the problem of estimating the unknown zero-symmetric distribution in a two-component location mixture model, considered in previous works, now under the…
Global Rates of Convergence of the MLEs of Log-concave and s-concave Densities
Charles R. Doss, Jon A. Wellner
We establish global rates of convergence for the Maximum Likelihood Estimators (MLEs) of log-concave and -concave densities on . The main finding is that the rate of…
Markov Chain Monte Carlo Estimation of Quantiles
Charles Doss, James M. Flegal, Galin L. Jones +1
We consider quantile estimation using Markov chain Monte Carlo and establish conditions under which the sampling distribution of the Monte Carlo error is approximately Normal. Furt…
Fitting birth-death processes to panel data with applications to bacterial DNA fingerprinting
Charles R. Doss, Marc A. Suchard, Ian Holmes +2
Continuous-time linear birth-death-immigration (BDI) processes are frequently used in ecology and epidemiology to model stochastic dynamics of the population of interest. In clinic…
