Robust testing to compare regression curves

  title={Robust testing to compare regression curves},
  author={Graciela Boente and Juan Carlos Pardo-Fern'andez},
This paper focuses on the problem of testing the null hypothesis that the regression functions of several populations are equal under a general nonparametric homoscedastic regression model. To protect against atypical observations, the test statistic is based on the residuals obtained by using a robust estimate for the regression function under the null hypothesis. The asymptotic distribution of the test statistic is studied under the null hypothesis and under root − n contiguous alternatives…

A Non‐parametric ANOVA‐type Test for Regression Curves Based on Characteristic Functions
This article studies a new procedure to test for the equality of k regression curves in a fully non‐parametric context. The test is based on the comparison of empirical estimators of the
Robust estimators under semi‐parametric partly linear autoregression: Asymptotic behaviour and bandwidth selection
Abstract.  In this article, under a semi‐parametric partly linear autoregression model, a family of robust estimators for the autoregression parameter and the autoregression function is studied. The
Robust Tests in Semiparametric Partly Linear Models
Abstract.  This paper focuses on the problem of testing the null hypothesis that the regression parameter equals a fixed value under a semiparametric partly linear regression model by using a

Testing heteroscedasticity in nonparametric regression
The importance of being able to detect heteroscedasticity in regression is widely recognized because efficient inference for the regression function requires that heteroscedasticity is taken into
Testing for the equality of k regression curves
Assume that (X-j, Y-j) are independent random vectors satisfying the nonparametric regression models Y-j = m(j) (X-j) + sigma(j) (X-j)epsilon(j), for j = 1, ... , k, where mj (X-j) = E(Y-j | X-j) and

Asymptotically optimal difference-based estimation of variance in nonparametric regression
SUMMARY We define and compute asymptotically optimal difference sequences for estimating error variance in homoscedastic nonparametric regression. Our optimal difference sequences do not depend on
