Robust Estimation and Model Selection for the Controlled Directed Effect with Unmeasured Mediator-Outcome Confounders
Shunichiro Orihara, Shinpei Imori, Kosuke Morikawa +2
Controlled Direct Effect (CDE) is one of the causal estimands used to evaluate both exposure and mediation effects on an outcome. When there are unmeasured confounders existing bet…
Semiparametric imputation using latent sparse conditional Gaussian mixtures for multivariate mixed outcomes
Shonosuke Sugasawa, Jae Kwang Kim, Kosuke Morikawa
This paper proposes a flexible Bayesian approach to multiple imputation using conditional Gaussian mixtures. We introduce novel shrinkage priors for covariate-dependent mixing prop…
Statistical Inference with Different Missing-data Mechanisms
Kosuke Morikawa, Yutaka Kano
When data are missing due to at most one cause from some time to next time, we can make sampling distribution inferences about the parameter of the data by modeling the missing-dat…
Identification Problem for The Analysis of Binary Data with Non-ignorable Missing
Kosuke Morikawa, Yutaka Kano
When a missing-data mechanism is NMAR or non-ignorable, missingness is itself vital information and it must be taken into the likelihood, which, however, needs to introduce additio…
