Estimation of a Discrete Choice Model When Individual Choices Are Not Observable
نویسنده
چکیده
This paper presents an econometric technique for circumventing the lack of individual choice data in a framework of binary choice model by utilizing aggregate choice data. The probability of observing a certain number of individuals making choice A out of the total number of individuals in a group is presented as a sum of probabilities of disjoint events, in which some individuals are picked to make choice A, and others are not. These probabilities are then used to form a likelihood function. The model, which is estimated using the method of maximum likelihood, performs favorably in an application to real discrete choice data.

On Calibration and Application of Logit-Based Stochastic Traffic Assignment Models
There is a growing recognition that discrete choice models are capable of providing a more realistic picture of route choice behavior. In particular, influential factors other than travel time that are found to affect the choice of route trigger the application of random utility models in the route choice literature. This paper focuses on path-based, logit-type stochastic route choice models, i...
متن کاملThe Occupation, Marriage, and Fertility Choices of Women: A Life-Cycle Model
An extensive literature in labor economics recognizes that the life-cycle labor force participation of a woman is highly associated with her family choices. There is, however, virtually no study going further to incorporate female occupational choices. This paper attempts to fill this gap in labor supply literature by examining the interrelatedness of occupation, marital status and fertility ch...
متن کاملModeling Discrete Choices in the Presence of Inertia and Serial Correlation
T concept of habit or inertia in the context of (reluctance to) change in travel behavior has an important bearing on transport policy (e.g., how to break car use habits) and has remained an unresolved issue in demand modeling. Another major problem in modeling the response to policy measures is the potential correlation or dependence between the choices made by a given individual over time (i....

There are a lot of techniques and methods for prediction of bankruptcy among them “Statistical methods” or econometrics techniques are more popular. As dependent variable in our study is qualitative it is convenient to use qualitative discrete models. Mixed Logit model is one of the powerful and flexible techniques of discrete choices that allow the coefficients to be random with distribution f...
متن کاملSemiparametric estimation of multinomial discrete-choice models using a subset of choices
Nonlogit maximum-likelihood estimators are inconsistent when using data on a subset of the choices available to agents. I show that the semiparametric, multinomial maximum-score estimator is consistent when using data on a subset of choices. No information is required for choices outside of the subset. The required conditions about the error terms are the same conditions as for using all the ch...
