Webtests the hypothesis that the residual correlation matrix, computed over observations common to all cross-sectional units, is an identity matrix of order Ng, where Ng is the number of cross-sectional units. The Lagrange multiplier test statistic is λLM = T Ng i=2 i−1 j=1 r2 ij where r2 ij is the ijth residual correlation coefficient. The ... Webfirst log在线中文翻译、first log读音发音、first log用法、first log例句等。 ...

WebHence, cross-sectional correlation is represented by means of a spatial process, which explicitly relates each unit to its neighbors (see Whittle (1954), Moran (1948), Cli⁄ and Ord (1973 and 1981), Anselin (1988 and 2001), Haining (2003, Chapter 7), and the recent survey by Lee and Yu (2013)).
