Fuzzy Random Utility Choice Models: The Case of Telecommuting Suitability

the application of multivariate probit models for conditional claim-types (the case study of iranian car insurance industry)

هدف اصلی نرخ گذاری بیمه ای تعیین نرخ عادلانه و منطقی از دیدگاه بیمه گر و بیمه گذار است. تعین نرخ یکی از مهم ترین مسایلی است که شرکتهای بیمه با آن روبرو هستند، زیرا تعیین نرخ اصلی ترین عامل در رقابت بین شرکتها است. برای تعیین حق بیمه ابتدا می باید مقدار مورد انتظار ادعای خسارت برای هر قرارداد بیمه را برآورد کرد. روش عمومی مدل سازی خسارتهای عملیاتی در نظر گرفتن تواتر و شدت خسارتها می باشد. اگر شر...

Modeling the choice of choice set in discrete-choice random-utility models

In conventional random-utility models, such as the multinomial logit model, it is assumed that a decisionmaker's choice set is independent of his or her preferences conditional on the explanatory variables of the models. However, there are many situations in which the decisionmaker chooses the choice set, thereby making the independence assumption implausible. For example, if information about ...

Utility of Complex Alternatives in Multiple-Choice Items: The Case of All of the Above

This study investigated the utility of all of the above (AOTA) as a test option in multiple-choice items. It aimed at estimating item fit, item difficulty, item discrimination, and guess factor of such a choice. Five reading passages of the Key English Test (KET, 2010) were adapted. The test was reconstructed in 2 parallel forms: Test 1 did not include the abovementioned alternative, whereas Te...

Random Utility-Based Discrete Choice Models for Travel Demand Analysis

Fuzzy Constraints, Choice, and Utility

We revisit the notion of fuzzy revealed preference, with the intention of using it in decision making. A decision making agent manages resources that are priced, and it has a certain wealth. We review proposed fuzzifications of preference relations. Although they are well founded, they cannot deal well with decision making under fuzzy constraints. We introduce the fuzzy budget set as a general ...

Incorporating Probabilistic Choice Rules within Random Utility Models of Brand Choice: Theory and Empirical Illustration

Existing random utility models of brand choice behavior, in the tradition of McFadden (1974), are based on the assumption that consumers employ the decision rule of maximum utility to choose a brand. However, there is a rich body of empirical work in mathematical psychology that suggests that consumers choose probabilistically between brands (see, for example, Luce 1959). In this paper, we prop...
