Sets of genes strongly correlated with a particular singular vector will have greater internal correlation.
Consequently, the internal correlation between the non-uniform inflow and performance deviation is revealed.
Therefore, vulnerability index is a formative measurement and the indicators chosen need not have internal correlation (ICRISAT 2006).
Some literature on index construction argues that a good measure of the validity of the index is the internal correlation between the individual indicators used in the index.
This suggests that changes in vector orientations upon activation represent changes in the internal correlation between voxels that is interpreted as a change in the internal neuronal communication.
Furthermore, a 30%and16%6% of reduction in external and internal correlation is obtained via this approach which is very promising.
In particular, studies in monkeys and humans have discovered a neural mirror system that demonstrates an internal correlation between the representations of perceptual and motor functionalities.
The SAE model does not need the prior defining features [9]; only through setting up the node numbers of hidden layer units, the hidden layer information of the target object images can be automatically learnt, and the essence of the internal correlation of the target object images can be obtained.
In the 'model-free' approach [1], [2], the internal dynamics are quantified using a generalized order parameter, S2, which characterizes the amplitude of motion, and an internal correlation time τi.
It has recently been reported that only about 30% of the modules defined by GO terms and 57% of the modules defined by KEGG pathways display an internal correlation higher than the expected by chance [14].
This undesirable property also applies to the main effects of the bivariate logistic model as we could confirm in simulation studies (only in the case of internal correlation in the gene sets, which is the case of gene expression but not of the rest of the measurements used in this study).
