TS-Neyman: Posterior Sampling for Adaptive Stratified Estimation

Kosuke Morikawa, Mst Moushumi Pervin, Jae Kwang Kim

Many model evaluation tasks reduce to estimating an average loss, error rate, or subgroup metric on a stratified pool when each label, human rating, or simulator call is costly. Th…

Semiparametric Efficient Data Integration Using the Dual-Frame Sampling Framework

Kosuke Morikawa, Jae Kwang Kim

Integrating probability and non-probability samples is increasingly important, yet unknown non-probability inclusion mechanisms complicate identification and efficient estimation.…

Efficient Multiple-Robust Estimation for Nonresponse Data Under Informative Sampling

Kosuke Morikawa, Kenji Beppu, Wataru Aida

Nonresponse after probability sampling is a universal challenge in survey sampling, often necessitating adjustments to mitigate sampling and selection bias simultaneously. This stu…

Identification enhanced generalised linear model estimation with nonignorable missing outcomes

Kenji Beppu, Jinung Choi, Kosuke Morikawa +1

Missing data often result in undesirable bias and loss of efficiency. These issues become substantial when the response mechanism is nonignorable, meaning that the response model d…
