Shape-based functional data analysis

Y Wu, C Huang, A Srivastava - Test, 2024 - Springer
Functional data analysis (FDA) is a fast-growing area of research and development in
statistics. While most FDA literature imposes the classical L 2 Hilbert structure on function …

Rates of the strong uniform consistency for the kernel-type regression function estimators with general kernels on manifolds

S Bouzebda, N Taachouche - Mathematical Methods of Statistics, 2023 - Springer
In the present paper, we develop strong uniform consistency results for the generic kernel

characteristics and contain rich information that cannot be obtained when regarding the data …

Test for the mean of high-dimensional functional time series

L Yang, Z Feng, Q Jiang - Computational Statistics & Data Analysis, 2025 - Elsevier
The one-sample test and two-sample test for the mean of high-dimensional functional time
