Glossary of game theory terms. Constant Sum. In a constant sum game, the sum of all players' payoffs is the same for any outcome. Hence, a gain for one participant is always at the expense of another, such as in most sporting events. Given the conflicting interests, the equilibrium of such games is often in mixed strategies.
The constant term in linear regression analysis seems to be such a simple thing. Also known as the y intercept, it is simply the value at which the fitted line crosses the y-axis.While the concept is simple, Iâve seen a lot of confusion about interpreting the constant.he slope is way off and the predicted values are biased. For the model without the constant, the weight predictions tend to be too high for shorter subjects and too low for taller subjects. In closing, the regression constant is generally not worth interpreting.
