A Wavelet-Based Independence Test for Functional Data with an Application to MEG Functional Connectivity
Rui Miao, Xiaoke Zhang, Raymond K. W. Wong
Measuring and testing the dependency between multiple random functions is often an important task in functional data analysis. In the literature, a model-based method relies on a m…
Low-Rank Covariance Function Estimation for Multidimensional Functional Data
Jiayi Wang, Raymond K. W. Wong, Xiaoke Zhang
Multidimensional function data arise from many fields nowadays. The covariance function plays an important role in the analysis of such increasingly common data. In this paper, we…
Broadcasted Nonparametric Tensor Regression
Ya Zhou, Raymond K. W. Wong, Kejun He
We propose a novel use of a broadcasting operation, which distributes univariate functions to all entries of the tensor covariate, to model the nonlinearity in tensor regression no…
Median Matrix Completion: from Embarrassment to Optimality
Weidong Liu, Xiaojun Mao, Raymond K. W. Wong
In this paper, we consider matrix completion with absolute deviation loss and obtain an estimator of the median matrix. Despite several appealing properties of median, the non-smoo…
