multigroup model

multigroup model

[′məl·tə‚grüp ′mäd·əl]
(nucleonics)
A model for the behavior of neutrons in a material in which they are grouped into several energy ranges, taking into account differences in spatial behavior of neutrons in the various groups, and transfer of neutrons between groups.

When we found such a model, we conducted further analyses to check for significant differences between the four different samples by estimating a multigroup model (cf.
In technical terms, this initial multigroup model is termed the configurai model (Horn & McArdle, 1992) and is the first and least restrictive one to be tested.
Second, working within the framework of a multigroup model, we tested for the invariance of the factor loadings and factor correlations across Group 2 (the calibration group) and Group 3 (the validation group).
Multigroup model estimated using Maximum Likelihood with robust error estimation (MLR).
In [3], Wen and Zhong studied an SIR model on bipartite networks and they proved the existence and the asymptotic stability of the endemic equilibrium by applying the theory of the multigroup model. In [4], Mishra and Jha proposed the following SEIQRS model to describe the transmission of malicious objects in computer network by introducing a new compartment quarantine into the SEIRS model proposed in [2]:
proposed a multigroup model to monitor batch processes with multiple modes [17].
By using the results or ideas of [15], the papers [16, 17] proved the global stability of the endemic equilibrium for multi-group model with nonlinear incidence rates and the papers [18, 19] proved the global stability of the endemic equilibrium for multigroup model with distributed delays.
These differences in batches both across and within reaction vessels must be accounted for in a singe multigroup model that will be required to 'model' all products being processed.
Model 2 was an unconstrained multigroup model that evaluated the general form of the full model for teachers from different preparation programs.
The results from multigroup model comparisons indicate that the factorial structure of these method effects was not significantly different for third and sixth graders.
We first tested a non-restricted multigroup model, in which all parameter estimates were allowed to differ between boys and girls.
