A New Test for One-Way ANOVA with Functional Data and Application to Ischemic Heart Screening
Jin-Ting Zhang, Ming-Yen Cheng, Chi-Jen Tseng +1
We propose and study a new global test, namely the -test, for the one-way ANOVA problem in functional data analysis. The test statistic is taken as the maximum value of t…
Nonparametric and adaptive modeling of dynamic seasonality and trend with heteroscedastic and dependent errors
Yu-Chun Chen, Ming-Yen Cheng, Hau-tieng Wu
Seasonality (or periodicity) and trend are features describing an observed sequence, and extracting these features is an important issue in many scientific fields. However, it is n…
Local Linear Regression on Manifolds and its Geometric Interpretation
Ming-Yen Cheng, Hau-tieng Wu
High-dimensional data analysis has been an active area, and the main focuses have been variable selection and dimension reduction. In practice, it occurs often that the variables a…
Reducing variance in univariate smoothing
Ming-Yen Cheng, Liang Peng, Jyh-Shyang Wu
A variance reduction technique in nonparametric smoothing is proposed: at each point of estimation, form a linear combination of a preliminary estimator evaluated at nearby points…
