Decision Tree Model. In computational complexity theory, the decision tree model is the model of computation in which an algorithm can be considered to be a decision tree, i.e. a sequence of queries or tests that are done adaptively, so the outcome of previous tests can influence the tests performed next.
The Vroom–Yetton contingency model is a situational leadership theory of industrial and organizational psychology developed by Victor Vroom, in collaboration with Philip Yetton (1973) and later with Arthur Jago (1988). The situational theory argues the best style of leadership is contingent to the situation.
Decision trees can also be seen as generative models of induction rules from empirical data. An optimal decision tree is then defined as a tree that accounts for most of the data, while minimizing the number of levels (or "questions"). [8] Several algorithms to generate such optimal trees have been devised, such as ID3/4/5, [9] CLS, ASSISTANT ...
Victor Vroom, a professor at Yale University and a scholar on leadership and decision-making, developed the normative model of decision-making. [1] Drawing upon literature from the areas of leadership, group decision-making, and procedural fairness, Vroom’s model predicts the effectiveness of decision-making procedures. [2]
An extensive-form representation is often used to analyze the Stackelberg leader-follower model. Also referred to as a “decision tree”, the model shows the combination of outputs and payoffs both firms have in the Stackelberg game. A Stackelberg game represented in extensive form. The image on the left depicts in extensive form a ...
Theorists defined the style of leadership as contingent to the situation; this is sometimes called contingency theory. Three contingency leadership theories are the Fiedler contingency model, the Vroom-Yetton decision model, and the path-goal theory.

Decision tree learning is a method commonly used in data mining. [3] The goal is to create a model that predicts the value of a target variable based on several input variables. A decision tree is a simple representation for classifying examples.
