where −1 ≤ρ≤ 1. However, the practical use of the correlation coefficient as a measure of dependence is justified only when the joint distribution of (X, Y) pairs is normal or approximately normal; the use of p as a measure of dependence between arbitraryYandXsometimes leads to errone...
We finally show that periodicities of 10–11 basepairs in yeast DNA originate from an alternation of hydrophobic and hydrophilic amino acids in protein sequences.doi:10.1016/S0378-4371(97)00505-0H HerzelE.N TrifonovO WeissI Gro?ePhysica A: Statistical Mechanics and its Applications...
We show quantitatively that the 3-basepair-periodicity is due to the nonuniformity of the codon usage in protein coding segments. We finally show that periodicities of 10–11 basepairs in yeast DNA originate from an alternation of hydrophobic and hydrophilic amino acids in protein sequences. 展开...
Between some pairs of functional imaging modalities moderate correlations were observed with respect to the median over all patient datasets, whereas distinct correlations were only present on an individual basis. Highest inter-modality median correlations on the voxel level were obtained for FDG/FMISO...
There's also one nominal variable that keeps the two measurements together in pairs, such as the name of an individual organism, experimental trial, or location. I'm not aware that anyone else considers this nominal variable to be part of correlation and regression, and it's not something ...
that weak correlations between pairs of neurons coexist with strongly collective behaviour in the responses of ten or more neurons. We find that this collective behaviour is described quantitatively by models that capture the observed pairwise correlations but assume no higher-order interactions. These...

Notice that ϕ′ provides a measure of the degree to which a gene’s expression is more variable than expected by chance, and PCC′ provides a metric by which gene-pairs are judged more positively or negatively correlated than expected by chance, correcting in both cases for unequal sequencin...

Considering the two variables “age” and “salary,” a strong positive correlation between the two would be expected: as people get older, they tend to earn more money. Therefore, the correlation between age and salary probably gives a value over 0.7.Figure 6.2illustrates pairs of numerical va...
