Analytic Standard Errors for Latent Gaussian Discrete-Valued Multivariate Time Series
Christopher M. Crawford, Marie-Christine Düker, Younghoon Kim +3
Unlike their continuous-valued counterparts, there are no universally preferred methodologies for modeling discrete-valued time series. This is especially problematic in fields suc…
Testing common structure in high-dimensional factor models: change-point and two-sample procedures
Marie-Christine Düker, Vladas Pipiras
This work proposes a novel procedure to test for common structures across two high-dimensional factor models. The introduced test allows to uncover whether two factor models are dr…
Prior distributions for structured semi-orthogonal matrices
Michael Jauch, Marie-Christine Düker, Peter Hoff
Statistical models for multivariate data often include a semi-orthogonal matrix parameter. In many applications, there is reason to expect that the semi-orthogonal matrix parameter…
Testing Simultaneous Diagonalizability
Yuchen Xu, Marie-Christine Düker, David S. Matteson
This paper proposes novel methods to test for simultaneous diagonalization of possibly asymmetric matrices. Motivated by various applications, a two-sample test as well as a genera…
