Correlations, spectral coherence and phase synchronization, which allow to understand the extent to which two variables are statistically connected or shared, influenced by a third variable, together with analyses of the directionality of these dynamical interactions, may potentially contribute to understanding the mechanism of pain processing in migraine.
However, if the settings in the test were not random, but instead influenced by a hidden variable, the results would be void and the experiment invalid.
Specifically, the three functions considered by the LFA were strongly influenced by a single variable relating to perennial vegetation cover, but were essentially unaffected by more subtle differences between site types, such as quantity of leaf litter or cover of grasses.
This apparent relationship could result from therapists discharging the child and providing a written assessment report as a discharge summary, or it could be that communicating assessment findings in writing is influenced by a confounding variable related to it and LoT (e.g. therapists' approach to communicating with parents).
Since methylation of several genes might be influenced by a single hidden variable, such as a methyltransferase mutation or environment, we also postulate a hidden (possibly multidimensional) variable V that may affect both M1 and M2.
Life expectancy in the 54 districts was influenced by a latent categorical variable, which consists of seven categories or clusters.
The covariation of these error types and sequence length indicates that they are influenced by a single latent variable.
Expanding the diverse detectable metabolome over a broad range of concentration, physical and chemical properties is challenging yet crucial since multiple pathways can often be influenced by a single external variable.
Latent class analysis (LCA) is based on the concept that observed results of different imperfect tests for the same disease are influenced by a latent common variable, the true disease status, which cannot be directly measured.
The reactions in S ɛ are instead influenced by a specifically defined variable ε, depending on a Hill function, fit against experimental data which quantify the platelet activation status, which is used to model the physiological levels of thrombin concentration as a function of platelet activation, as thoroughly described in [ 30].
