Testing lack of fit of regression models under heteroscedasticity
A test is proposed for assessing the lack of fit of heteroscedastic nonlinear regression models that is based on comparison of nonparametric kernel and parametric fits. A data-driven method is proposed for bandwidth selection using the parametric null model asymptotically optimal bandwidth which leads to a test that has a limiting normal distribution under the null hypothesis and is consistent ...
متن کاملVoronoi Residuals and their Application in Assessing the Fit of Poin Process Models: An Applied Study
Many point process models have been proposed for studying variety of scientific disciplines, including geology, medicin, astronomy, forestry, ecology and ect. The assessment of fitting these models is important. Residuals-based methods are appropriate tools for evaluating good fit of spatial point of process models. In this paper, first, the concepts related to the Voronoi ...
متن کاملTesting Lack-of-fit of Parametric Regression Models Using Nonparametric Regression Techniques
Data-driven lack-of-fit tests are derived for parametric regression models using fit comparison statistics that are based on nonparametric linear smoothers. The tests are applicable to settings where the usual bandwidth/smoothing parameter asymptotics apply to the null model, which includes testing for nonlinear models and some linear models. Large sample distribution theory is established for ...
متن کاملNonparametric lack-of-fit tests for parametric mean-regression models with censored data
We develop two kernel smoothing based tests of a parametric mean-regression model against a nonparametric alternative when the response variable is rightcensored. The new test statistics are inspired by the synthetic data and the weighted least squares approaches for estimating the parameters of a (non)linear regression model under censoring. The asymptotic critical values of our tests are give...
متن کاملRegional residual plots for assessing the fit of linear regression models
An intuitively appealing lack-of-fit test to assess the adequacy of a regression model is introduced together with a graphical diagnostic tool. The graphical method itself includes a formal testing procedure, and, it is particularly useful to detect the location of lack-of-fit. The procedure is based on regional residuals, using subsets of the space of the independent variables. A simulation st...
