It should be evident from this observation that there is definitely a connection between the sign of the correlation coefficient and the slope of the least squares line. It remains to explain why this is true. The Formula for the Slope The reason for the connection between the value ofrand t...

The formula for the test statistic ist=r√n−2√1−r2t=rn−21−r2. The value of the test statistic,t, is shown in the computer or calculator output along with thep-value. The test statisticthas the same sign as the correlation coefficientr. ...

(3) is tested by the Armey curve hypothesis using the signs of the coefficients \({b}_{1}\) and \({b}_{2}\). In other words, an inverted U-shaped curve is confirmed if b1 has a positive and b2 has a negative sign. The methodology for conducting the empirical analysis in this ...
We show a few consistent patterns in the correlations between the scores for the vulnerability of the grid and the optimal clusters. The strength and sign of the correlation coefficients depend on the different electrical factors weighting the transmission lines and the grid-specific topology....

Each monomial can be easily explained, for example, the first monomial in the WH transform, that is 12x1x4, indicates that mutation sites 1 and 4 are interacting and the interaction enriches fitness because the sign of the coefficient is positive. On the hand, the second monomial − ...
