Geodesic synthetic control methods for random objects and functional data

Daisuke Kurisu, Hans-Georg Mueller, Taisuke Otsu and Yidong Zhou

We introduce a geodesic synthetic control method for causal inference that extends existing synthetic control methods to scenarios where outcomes are elements in a geodesic metric space rather than scalars. Examples of s...Read more...

Geodesic difference-in-differences

Daisuke Kurisu, Hans-Georg Mueller, Taisuke Otsu and Yidong Zhou

Difference-in-differences (DID) is a widely used quasi-experimental design for causal inference, traditionally applied to scalar or Euclidean outcomes, while extensions to outcomes residing in non-Euclidean spaces remain...Read more...

Geodesic causal inference

Daisuke Kurisu, Hans-Georg Mueller, Taisuke Otsu and Yidong Zhou

Adjusting for confounding and imbalance when establishing statistical relationships is an increasingly important task, and causal inference methods have emerged as the most popular tool to achieve this. Causal inference ...Read more...

Empirical likelihood for manifolds

Daisuke Kurisu and Taisuke Otsu

There has been growing interest in statistical analysis on random objects taking values in a non-Euclidean metric space. One important class of such objects consists of data on manifolds. This article is concerned with i...Read more...

Nonparametric causal inference with functional covariates

Daisuke Kurisu, Taisuke Otsu and Mengshan Xu

Functional data and their analysis have become increasingly popular in various fields of data sciences. This paper considers estimation and inference of the average treatment effect under unconfoundedness when the covari...Read more...

Model averaging for global Fréchet regression

Daisuke Kurisu and Taisuke Otsu

Petersen and Müller (2019) generalized the notion of regression analysis to non-Euclidean response objects. Meanwhile, in the conventional regression analysis, model averaging has long history and is widely applied in st...Read more...

Nonparametric inference for extremal conditional quantiles

Daisuke Kurisu and Taisuke Otsu

This paper studies asymptotic properties of the local linear quantile estimator under the extremal order quantile asymptotics, and develops a practical inference method for conditional quantiles in extreme tail areas. By...Read more...

On linearization of nonparametric deconvolution estimators for repeated measurements model

Daisuke Kurisu and Taisuke Otsu

By utilizing intermediate Gaussian approximations, this paper establishes asymptotic linear representations of nonparametric deconvolution estimators for the classical measurement error model with repeated measurements. ...Read more...

On the uniform convergence of deconvolution estimators from repeated measurements

Daisuke Kurisu and Taisuke Otsu

This paper studies the uniform convergence rates of Li and Vuong's (1998) nonparametric deconvolution estimator and its regularized version by Comte and Kappus (2015) for the classical measurement error model, where repe...Read more...
