Asymptotic Uniform False Discovery Rate Control for Inference of Time-varying Correlations
Bufan Li, Lujia Bai, Weichi Wu
Inference for locally stationary time series is challenging because the associated hypotheses form an uncountable collection over a continuous time interval, making pointwise false…
Measuring deviations from spherical symmetry
Lujia Bai, Holger Dette
Most of the work on checking spherical symmetry assumptions on the distribution of the -dimensional random vector has its focus on statistical tests for the null hypothesis…
F-scheduler: illuminating the free-lunch design space for fast sampling of diffusion models
Zilai Li, Lujia Bai
Diffusion models are the state-of-the-art generative models for high-resolution images, but sampling from pretrained models is computationally expensive, motivating interest in fas…
A portmanteau test for multivariate non-stationary functional time series with an increasing number of lags
Lujia Bai, Holger Dette, Weichi Wu
Multivariate locally stationary functional time series provide a flexible framework for modeling functional data exhibiting both temporal and spatial dependencies while allowing fo…
