Discrete Choice
Classical consumer theory assumes that products are infinitely divisible and consumers may purchase fractional quantities as dictated by their preferences and budget sets. However,for many goods and services individuals purchase only a few and sometimes at most one. Thus classical models of discrete choice in economics were developed to extend consumer choice theory to model demand of discrete ...
متن کاملDetecting, Non-Transitive, Inconsistent Responses in Discrete Choice Experiments
Surveys focusing on choice behaviour, and in particular, Discrete Choice Experiments (DCEs) are widely used in studies across many disciplines, including transportation, marketing research, health economics, labour economics and environmental studies. Investigation of the 'rationality' of responses in choice experiments has received a fair bit of attention from researchers. Most of this researc...
متن کاملDiscrete Choice Models for Non-Intrusive Quality Assessment
Non-intrusive signal quality assessment in general, and its application to speech signal processing, in particular, builds extensively upon statistical regression models. Commonly, the raw preference scores used for fitting these models belong to a categorical scale. Averaging the scores over a number of test subjects results in smooth, close-to-continuous ratings, thus justifying the use of re...
متن کاملDiscrete Choice and Censoring
Multinomial Choice: Data consists of consumer choices of various goods, along char acteristics. Let there be J choices and y = (y1, . . . , yJ ) where yj = 1 if good j is chosen and yj = 0 otherwise. Let x be observed characteristics of the goods and choices. Here a conditional density for y corresponds to conditional choice probabilities P (j|x, β), one for each j, with �J j=1 P (j|x, β) = 1 ...
