Sensitivity analysis for causal mediation: bridge score, sharp sensitivity bounds, and calibration
Yuki Ohnishi, Fan Li
Causal mediation analysis decomposes the total treatment effect into a portion operating through a hypothesized mediator and a residual direct portion. Identification of natural di…
Bayesian change-plane regression
Yuki Ohnishi, Fan Li
Change-plane regression represents treatment effect heterogeneity through an interpretable rule that assigns patients to two groups according to whether a linear score of baseline…
Locally Private Causal Inference for Randomized Experiments
Yuki Ohnishi, Jordan Awan
Local differential privacy is a differential privacy paradigm in which individuals first apply a privacy mechanism to their data (often by adding noise) before transmitting the res…
Degree of Interference: A General Framework For Causal Inference Under Interference
Yuki Ohnishi, Bikram Karmakar, Arman Sabbaghi
One core assumption typically adopted for valid causal inference is that of no interference between experimental units, i.e., the outcome of an experimental unit is unaffected by t…
A Bayesian Analysis of Two-Stage Randomized Experiments in the Presence of Interference, Treatment Nonadherence, and Missing Outcomes
Yuki Ohnishi, Arman Sabbaghi
Three critical issues for causal inference that often occur in modern, complicated experiments are interference, treatment nonadherence, and missing outcomes. A great deal of resea…
Bayesian Hierarchical Bernoulli-Weibull Mixture Model for Extremely Rare Events
Yuki Ohnishi, Shinsuke Sugaya
Estimating the duration of user behavior is a central concern for most internet companies. Survival analysis is a promising method for analyzing the expected duration of events and…
Applying Bayesian Hierarchical Probit Model to Interview Grade Evaluation
Yuki Ohnishi, Shinsuke Sugaya
Job interviews are a fundamental activity for most corporations to acquire potential candidates, and for job seekers to get well-rewarded and fulfilling career opportunities. In ma…
Novel Change of Measure Inequalities with Applications to PAC-Bayesian Bounds and Monte Carlo Estimation
Yuki Ohnishi, Jean Honorio
We introduce several novel change of measure inequalities for two families of divergences: -divergences and -divergences. We show how the variational representation for -d…
