Ordination or gradient analysis, in multivariate analysis, is a method complementary to data clustering, and used mainly in exploratory data analysis (rather than in hypothesis testing). In contrast to cluster analysis, ordination orders quantities in a (usually lower-dimensional) latent space. In the ordination space, quantities that are near ...
Goal progress is a measure of advancement toward accomplishment of a goal. [2] Perceptions of progress often impact human motivation to pursue a goal. [3] Hull (1932, 1934) developed the goal gradient hypothesis, which posits that motivation to accomplish a goal increases monotonically from the goal initiation state to the goal ending state.
In cognitive science and behavioral economics, loss aversion refers to a cognitive bias in which the same situation is perceived as worse if it is framed as a loss, rather than a gain. [ 1 ] [ 2 ] It should not be confused with risk aversion , which describes the rational behavior of valuing an uncertain outcome at less than its expected value .
Galton's experimental setup "Standard eugenics scheme of descent" – early application of Galton's insight [1]. In statistics, regression toward the mean (also called regression to the mean, reversion to the mean, and reversion to mediocrity) is the phenomenon where if one sample of a random variable is extreme, the next sampling of the same random variable is likely to be closer to its mean.
Daniel Kahneman, who won the 2002 Nobel Memorial Prize in Economics for his work developing prospect theory. Prospect theory is a theory of behavioral economics, judgment and decision making that was developed by Daniel Kahneman and Amos Tversky in 1979. [1] The theory was cited in the decision to award Kahneman the 2002 Nobel Memorial Prize in ...
Behavioral game theory analyzes interactive strategic decisions and behavior using the methods of game theory, [2] experimental economics, and experimental psychology. Experiments include testing deviations from typical simplifications of economic theory such as the independence axiom [3] and neglect of altruism, [4] fairness, [5] and framing ...
Behavioral economics is the study of the psychological (e.g. cognitive, behavioral, affective, social) factors involved in the decisions of individuals or institutions, and how these decisions deviate from those implied by traditional economic theory. [1] [2] Behavioral economics is primarily concerned with the bounds of rationality of economic ...
In economics, aggregate behavior refers to economy-wide sums of individual behavior. It involves relationships between economic aggregates such as national income, government expenditure, and aggregate demand. For example, the consumption function is a relationship between aggregate demand for consumption and aggregate disposable income.
