Testing Goodness-of-Fit of Parametric Spatial Trends. Proceedings 2018, 2, 1185.2504-3900http://hdl.handle.net/2183/21122Trátase dun resumo estendido da ponencia[Abstract] The aim of this work is to propose and analyze the behavior of a test statistic to assess a parametric trend surface, that is, a regression model with spatially correlated errors. The asymptotic behavior under the null hypothesis, as well as the asymptotic power of the test under local alternatives will be analyzed. Finite sample performance of the test is addressed by simulation, introducing a bootstrap calibration procedure.engAtribución 3.0 Españahttp://creativecommons.org/licenses/by/3.0/es/Model checkingSpatial trendLocal linear regressionLeast squaresBootstrapconference outputopen access10.3390/proceedings2181185
