摘要：The analysis of moment structural models has become an important tool of investigation in behavioral, educational and economic studies. The chi-squared large-sample test is routinely employed to assess the goodness of fit of the model considered. To invoke the standard asymptotic distribution theory certain regularity conditions have to be met. The case where the population value of the parameter vector is a boundary point of the feasible region is considered. In this case the asymptotic distr...
