DISTRIBUTED COMPUTING IN MULTI-GROUP STRUCTURAL EQUATION MODEL
This paper firstly proposes an improved partial least square(PLS) algorithm in structural equation model (SEM) using a suitable iterative initial value with constraint of unit vector.The algorithm enhances the convergence rate greatly and its convergency is illuminated. Then multi-group SEM is investigated and distributed computing is adopted to calculate all the coefficients in SEM of each group, which results in considerable timesavings when compared with traditional approach. Furthermore, a uniform model is built using the generalized linear model with convex constraint and an algorithm for the multi-group SEM is presented. The results of this paper have been received in software DASC.
