Choice modelling attempts to model the decision process of an individual or segment via revealed preferences or stated preferences made in a particular context or contexts. Typically, it attempts to use discrete choices (A over B; B over A, B & C) in order to infer positions of the items (A, B and C) on some relevant latent scale (typically ...
A Choice Set in discrete choice models is defined to be finite, exhaustive, and mutually exclusive. For instance, consider households' choice of how many laptops to own. The researcher can define the choice set depending on the nature of the data and the interpretation they wish to draw, as long as it satisfies three properties mentioned above.
The exploded logit model is the product of standard logit models with the choice set decreasing as each alternative is ranked and leaves the set of available choices in the subsequent choice. Without loss of generality, the alternatives can be relabeled to represent the person's ranking, such that alternative 1 is the first choice, 2 the second ...
Hybrid choice models are advanced econometric tools used to capture the decision-making processes of individuals by integrating both observable and unobservable factors. Traditional choice models , such as discrete choice models, rely solely on observable variables and choices made by individuals to infer preferences and predict future behavior.

Best–worst scaling (BWS) [1] techniques involve choice modelling (or discrete choice experiment – "DCE") and were invented by Jordan Louviere in 1987 while on the faculty at the University of Alberta. In general with BWS, survey respondents are shown a subset of items from a master list and are asked to indicate the best and worst items (or ...
Estimation of dynamic discrete choice models is particularly challenging, due to the fact that the researcher must solve the backwards recursion problem for each guess of the structural parameters. The most common methods used to estimate the structural parameters are maximum likelihood estimation and method of simulated moments .
The rational choice model, also called rational choice theory refers to a set of guidelines that help understand economic and social behaviour. [1] The theory originated in the eighteenth century and can be traced back to the political economist and philosopher Adam Smith . [ 2 ]
