Testing for Unobserved Heterogeneity in Censored Duration Models: EM Approach

Hiroyuki Kasahara, Hirokazu Matsuyama, Katsumi Shimotsu +1

Ignoring unobserved heterogeneity in duration models biases parameter estimates and invalidates inference, but testing for it is non-regular: the null hypothesis lies on the bounda…

On prediction-powered inference for quantile regression via convolution smoothing

Shota Takeishi, Jimin Ding, Xuming He

This paper studies quantile regression in a data-limited setting where the gold-standard outcome is available only for a limited number of observations, whereas a surrogate outcome…

Scalable Estimation of Crossed Random Effects Models via Multi-way Discretization

Shota Takeishi, Shonosuke Sugasawa

Cross-classified data frequently arise in scientific fields such as education, healthcare, and social sciences. A common modeling strategy is to introduce crossed random effects wi…

A Shrinkage Likelihood Ratio Test for High-Dimensional Subgroup Analysis with a Logistic-Normal Mixture Model

Shota Takeishi

In subgroup analysis, testing the existence of a subgroup with a differential treatment effect serves as protection against spurious subgroup discovery. Despite its importance, thi…

Asymptotic Properties of the Maximum Smoothed Partial Likelihood Estimator in the Change-Plane Cox Model

Shota Takeishi

The change-plane Cox model is a popular tool for the subgroup analysis of survival data. Despite the rich literature on this model, there has been limited investigation into the as…
