Nonlinear regression model checking via local polynomial smoothing
(2007-05-14)
A goodness-of-fitt test statistic for nonlinear regression models based on local polynomial estimation is proposed in this paper. The criterion used to construct the test is the distance between the parametric fitt and the ...
Bootstrap tests for nonparametric comparison of regression curves with dependent errors
(Springer, 2007)
In this paper, the problem of testing the equality of regression curves with dependent data is studied. Several methods based on nonparametric estimators of the regression function are described. In this setting, the ...
