Two New Tests for Equality of Several Covariance Functions
Jia Guo, Jin-Ting Zhang
In this paper, we propose two new tests for testing the equality of the covariance functions of several functional populations, namely a quasi GPF test and a quasi test.…
A Supremum-Norm Based Test for the Equality of Several Covariance Functions
Jia Guo, Bu Zhou, Jin-Ting Zhang
In this paper, we propose a new test for the equality of several covariance functions for functional data. Its test statistic is taken as the supremum value of the sum of the squar…
A Further Study of an -norm Based Test for the Equality of Several Covariance Functions
Jia Guo, Jin-Ting Zhang
For the multi-sample equal covariance function (ECF) testing problem, Zhang (2013) proposed an -norm based test. However, its asymptotic power and finite sample performance…
Forward variable selection for sparse ultra-high dimensional varying coefficient models
Ming-Yen Cheng, Toshio Honda, Jin-Ting Zhang
Varying coefficient models have numerous applications in a wide scope of scientific areas. While enjoying nice interpretability, they also allow flexibility in modeling dynamic imp…
