Structural equation modeling (SEM) is a multivariate statistical technique designed to model the structure of a covariance matrix (sometimes the structure of a mean vector as well) with a relatively few parameters, and to test the adequacy of such a hypothesized covariance (mean) structure in its...
In this article we derive a test statistic generating equation (TSGE) from which several statistics suitable for testing parametric restrictions in models estimated by the generalized method of moments (GMM) may be obtained. This statistic presents three main features: it is valid for producing ...
However, the purpose of structural equation modeling (SEM) is to identify a model and use it to account for the relationship among substantive variables. With the setup of NHT, a nonsignificant test statistic does not necessarily imply that the model is correctly specified or the size of ...

Moran’s index is an important spatial statistical measure used to determine the presence or absence of spatial autocorrelation, thereby determining the selection orientation of spatial statistical methods. However, Moran’s index is chiefly a statistica
(e.g., the likelihood ratio chi-squared test), then other conceptually contradictory measures are usually reported (e.g., the NNFI). In addition, it is not uncommon to find numerous modifications made to an ill-fitting model to bring it in line with the data, usually supplemented bypost ...

You can find the predicted value either for a data point or for a new value of X. Each of your data points has a residual, which tells you how far the point is above (or below, if negative) the line. These residuals allow you to make adjustments, comparing actual values of Y with...
Or, as Aral and Van Alstyne (2011) find, access to novel information may also be dependent on the rate at which information is provided to an ego via their redundant or nonredundant ties. Given that we do not have data to determine whether this is the case, we believe future research ...
