The first editorial board meeting of the World Journal of Hepatology(WJH)was held on November 8,2019 at the Side Bar Grille,Sheraton Boston Hotel,Boston,MA,United States.Ruo-Yu Ma,Director of Editorial Office,on behalf of the Baishideng Publishing Group(BPG),organized the meeting with the great help of Professor Ke-Qin Hu,Journal Editor-in-Chief.There were six editorial board members,including two Editors-in-Chief and one administrative director of the editorial office at the meeting,discussing future strategies of the journal’s development.The editorial board provided BPG a number of suggestions in regard to the business plan and quality control of the WJH.Regarding the business aspect,the editorial board suggested that BPG should advertise the WJH at the international Hepatology and Gastroenterology conferences and promote the WJH via social media.On the scientific aspect,the editorial board suggested that the assessment systems for managing the reviewers and the editorial board members are necessary,and that the BPG should make efforts to attract more high-quality manuscript submissions.An additional comment was to continue to foster a scientific culture for the journal.In conclusion,it was noted that these new ideas expressed during the meeting will bring the WJH to the next level.In the future,the BPG and the editorial board will increase communication and collaboration in order to further the development of the WJH. 展开更多

Objectives: The objective is to analyze the interaction of the correlation structure and values of the regressor variables in the estimation of a linear model when there is a constant, possibly negative, intra-class correlation of residual errors and the group sizes are equal. Specifically: 1) How does the variance of the generalized least squares (GLS) estimator (GLSE) depend on the regressor values? 2) What is the bias in estimated variances when ordinary least squares (OLS) estimator is used? 3) In what cases are OLS and GLS equivalent. 4) How can the best linear unbiased estimator (BLUE) be constructed when the covariance matrix is singular? The purpose is to make general matrix results understandable. Results: The effects of the regressor values can be expressed in terms of the intra-class correlations of the regressors. If the intra-class correlation of residuals is large, then it is beneficial to have small intra-class correlations of the regressors, and vice versa. The algebraic presentation of GLS shows how the GLSE gives different weight to the between-group effects and the within-group effects, in what cases OLSE is equal to GLSE, and how BLUE can be constructed when the residual covariance matrix is singular. Different situations arise when the intra-class correlations of the regressors get their extreme values or intermediate values. The derivations lead to BLUE combining OLS and GLS weighting in an estimator, which can be obtained also using general matrix theory. It is indicated how the analysis can be generalized to non-equal group sizes. The analysis gives insight to models where between-group effects and within-group effects are used as separate regressors. 展开更多
