Nonparametric significance testing and group variable selection

Zambom, Adriano Zanin; Akritas, Michael G. - In: Journal of Multivariate Analysis 133 (2015) C, pp. 51-60

In the context of a heteroscedastic nonparametric regression model, we develop a test for the null hypothesis that a subset of the predictors has no influence on the regression function. The test uses residuals obtained from local polynomial fitting of the null model and is based on a test...

Robust comparison of regression curves

Feng, Long; Zou, Changliang; Wang, Zhaojun; Zhu, Lixing - In: TEST: An Official Journal of the Spanish Society of … 24 (2015) 1, pp. 185-204

<Para ID="Par1">This paper is concerned about robust comparison of two regression curves. Most of the procedures in the literature are least-squares-based methods with local polynomial approximation to nonparametric regression. However, the efficiency of these methods is adversely affected by outlying...</para>
