A prevailing challenge in the biomedical and social sciences is to estimate a population mean from a sample obtained with unknown selection probabilities. Using a well-known ratio estimator, Aronow and Lee (2013) proposed a method for partial identification of the mean by allowing the unknown selection probabilities to vary arbitrarily between two fixed extreme values. In this paper, we show how to leverage auxiliary shape constraints on the population outcome distribution, such as symmetry or…

An Interval Estimation Approach to Sample Selection Bias

A widespread and largely unaddressed challenge in statistics is that non-random participation in study samples can bias the estimation of parameters of interest. To address this problem, we propose a

Sample-constrained partial identification with application to selection bias

Many partial identification problems can be characterized by the optimal value of a function over a set where both the function and set need to be estimated by empirical data. Despite some progress

An Interval Estimation Approach to Selection Bias in Observational Studies

A persistent challenge in observational studies is that non-random participation in study samples can result in biased estimates of parameters of interest. To address this problem, we present a

Sensitivity analysis for inverse probability weighting estimators via the percentile bootstrap

To identify the estimand in missing data problems and observational studies, it is common to base the statistical estimation on the ‘missingness at random’ and ‘no unmeasured confounder’ assumptions.

Design-Based Uncertainty for Quasi-Experiments

Social scientists are often interested in estimating causal effects in settings where all units in the population are observed (e.g. all 50 US states). Design-based approaches, which view the

Bounds and semiparametric inference in $L^\infty$- and $L^2$-sensitivity analysis for observational studies

Sensitivity analysis for the unconfoundedness assumption is a crucial component of observational studies. The marginal sensitivity model has become increasingly popular for this purpose due to its

Bounds on the conditional and average treatment effect with unobserved confounding factors

A loss minimization approach that quantifies bounds on the conditional average treatment effect (CATE) when unobserved confounder have a bounded effect on the odds of treatment selection and a semi-parametric framework that extends/bounds the augmented inverse propensity weighted (AIPW) estimator for the ATE beyond the assumption that all confounders are observed.

Sharp Sensitivity Analysis for Inverse Propensity Weighting via Quantile Balancing

Inverse propensity weighting (IPW) is a popular method for estimating treatment effects from observational data. However, its correctness relies on the untestable (and frequently implausible)

Testing weak nulls in matched observational studies.

We develop sensitivity analyses for the sample average treatment effect in matched observational studies while allowing unit-level treatment effects to vary. The methods may be applied to studies

Covariate Balancing Sensitivity Analysis for Extrapolating Randomized Trials across Locations

The ability to generalize experimental results from randomized control trials (RCTs) across locations is crucial for informing policy decisions in targeted regions. Such generalization is often



Interval estimation of population means under unknown but bounded probabilities of sample selection

Applying concepts from partial identification to the domain of finite population sampling, we propose a method for interval estimation of a population mean when the probabilities of sample selection

Semiparametric Exponential Families for Heavy-Tailed Data

We propose a semiparametric method for fitting the tail of a heavy-tailed population given a relatively small sample from that population and a larger sample from a related background population. We

The modeling of multivariate extremes has received increasing recent attention because of its importance in risk assessment. In classical statistics of extremes, the joint distribution of two or more
