The phrase "a cluster of correlations" is correct and usable in written English.
It can be used when discussing multiple relationships or connections between variables in a statistical or analytical context.
Example: "The study revealed a cluster of correlations between socioeconomic status and health outcomes, indicating that various factors are interconnected."
Alternatives: "a group of correlations" or "a set of correlations".
We observed a cluster of negative correlation between response to these 2 variables in the vicinity of the dmPFC/ACC, with peaks at −2, 28, 30 (z = 3.17, P < 0.001, uncorrected) and −6, 36, 30 (z = −3.34, P < 0.0005, uncorrected; Fig. 4 a, left).
So, in digestive glands a cluster of genes with strong correlations included SOD, COI, CAT and, also, HSP90.
Unexpectedly, for each syndrome scale, we also found and replicated a cluster of frontal locations with inverse correlations, showing that the milder symptoms correspond to greater hyper-synchronization.
A cluster of transcripts with very strong correlation to P concentrations in the leaves could be identified.
In order to address the issues stated above, we now propose to investigate what may happen if affinity zones remain distinct from each other inside a cluster of receptors, but "weak" spatial correlation is still induced by placing receptors contiguously.
Islet tumors were identified by a cluster of 311 genes with elevated expression (correlation ≥0.75).
For example, many signatures that are likely tracking proliferation were commonly selected including the OncotypeDX RS [ 5], a signature of chromosomal instability (CIN70) [ 21], and two signatures that recapitulates the loss of the retinoblastoma gene [ 17, 18], all of which showed a cluster correlation of ~0.8 (Additional File 2).
A group-level analysis conducted only in the right hemisphere identified a prominent cluster of negative correlations between language functional MRI laterality index values and grey matter, indicating higher density in right posterior temporo-parietal cortex with increasing right-sided language lateralization (Fig. 4).
Interestingly, a single cluster of positive correlation in the PLIC of the contralesional hemisphere was found (Supplementary information), where greater FCR for the paretic leg was associated with increased FA.
There was, however, a strong clustering of significant correlations in the regions of previously linked to recency memory.
