We should avoid any claim regarding a correlation at the individual level [ 33].
A correlation at the amino acid level between two positions i and j may (top left) or may not (top right) be accompanied by a correlation at the codon level.
Consistent with this view, we did find a correlation at the individual level between Wolbachia titer and wasp ploidy.
There were few data to support such a correlation at the time our trial was designed; consequently, thyroid function measurement was not part of the clinical protocol.
Miranda et al. (2006) found a correlation at the population level between chloramination of drinking water and blood lead levels of children under 6 years of age.
The key premise underlying the method introduced here is that a correlation at the amino acid level between two positions is more likely to reflect a direct interaction if the correlation at the codon level for these positions is weak.
The Intego time series is again used as the input data set, therefore a correlation at lag minus 1 represents the relation between the changes in the Intego data at weekn and the changes in the EISS data at weekn+1.
The Intego time series is used as the input data set, therefore a correlation at lag minus 1 represents the relation between the Intego data at weekn and the EISS data at weekn+1.
A large positive or negative LSA value indicates a correspondingly strong PCC correlation or a correlation at a time displacement within the lag window.
Unlike in several other species, we found a lack of any correlation at the individual level (i.e. across individuals) between song features and ambient noise.
The paper also builds a partial equilibrium model predicting a positive correlation at the firm level between firm size, output quality, number and remoteness of output markets, employees' average education, and wages within each education level.
