Accounting for the potential false absences in the dataset allows the possibility that the presences of hybrids and P. eos were either positively or negatively correlated (maximum negative correlation: odds ratio = 0, p<0.001; maximum positive correlation: odds ratio = infinite, p<0.001).
Shubina and Lee (2004) showed that the maximum positive correlation of (5) is effected by concentrating all its mass on the (NE-SW) quadrants: {(x,y):(x - x0)(y - y0) ≥ 0}, and for the negative, on the (NW-SE) quadrants: {(x,y):(x - x0)(y - y0) ≤ 0}, for some real numbers x0 and y0.
There was also no significant correlation between the presences of hybrids and P. neogaeus, regardless of how the false absences are accounted for (maximum negative correlation: odds ratio = 0.63, p = 0.3104; maximum positive correlation: odds ratio = 2.01, p = 0.0999).
The correlation plots reveal a wide range of correlation coefficients among all of the measured metabolites, ranging from 1.0 (maximum positive correlation) to −1.0 (maximum anticorrelation) and 0 indicating no correlation.
There was a negative correlation between the presences of P. eos and P. neogaeus (odds ratio = 0.20, p = 0.0238), and accounting for false absences allows only the possibility of a negative correlation (maximum negative correlation: odds ratio = 0, p<0.001; maximum positive correlation: odds ratio = infinite, p = 0.5728).
For the value of bicor from −1 to 1, −1 represents the maximum negative correlation and 1 represents the maximum positive correlation.
Maxima (positive correlation) and minima (negative or anti-correlation) can be clearly distinguished, with a strong anti-correlation for genes that lie opposite of each other on the chromosome (a gene distance of around 650).
It is thus flexible enough to accommodate nearly the maximum positive (negative) correlation.
The lag is defined by the maximum positive lagged correlation between the OBP and the temperature, and its sign is defined to be positive when the OBP variation lags behind the temperature.
The neomenthone had direct positive effect (0.557) as well maximum positive genotypic correlation for menthofuran content and showed positive indirect effect via other quality traits except limonene (−0.263) and pulegone (−0.215).
The second LV showed a task main effect (singular value = 152.44, P < 0.016, task demands LV, Fig. 6, see Table 2 for a list of local maxima), with positive correlations for temporal sequencing tasks and negative for comparison tasks.
