Testing for elliptical symmetry of errors in the multivariate linear regression model

Yan Su, Shaoyue Kang
This paper presents a characteristic test for testing the elliptical distribution of the errors in the multivariate linear regression model. We obtain the asymptotic spherical distribution of the transformed residuals of the regression model under the null hypothesis. Based on bootstrap approximation,...

Study on satellite altimeter sea state bias estimation comprehensive model

Hongli Miao, Xin Wang, Guizhong Wang, Guoshou Zhang, Jie Zhang
The sea state bias (SSB) is one of the most prominent errors in satellite altimetry. The empirical model was mostly used in practical estimation of SSB, which includes the parametric model and nonparametric model. The estimation of SSB for the global area will result to large deviation with a single...
