linear regression

a regression analysis in which the predictor or independent variables (xs) are assumed to be related to the criterion or dependent variable (y) in such a manner that increases in an x variable result in consistent increases in the y variable. In other words, the direction and rate of change of one variable is constant with respect to changes in the other variable. The analysis yields a regression equation that includes an intercept and regression coefficients for the predictors. Compare nonlinear regression.

Machiavellian hypothesis

the hypothesis that the evolution of intelligence, especially in its social aspects, was largely dependent on behavior characterized by a desire and striving for power. According to the hypothesis, individuals who are more Machiavellian in their behavior are more likely to be successful in adaptation and thus more likely to spread their genes to future generations. [Niccolò Machiavelli (1469–1527), Italian political theorist]
