This paper presents an ordered logit approach to model the optimal timing of buying a house in the life cycle. The model is applied to three recent Belgian household budget surveys. We find that households postpone homeownership or choose to be lifelong tenant due to an increase of the transaction tax rate, the real interest rate on mortgages and an indicator for the evolution of real house pri...

BACKGROUND Laparoscopic surgery for common bile duct stones varies procedurally from a transcystic approach to laparoscopic choledochotomy (LC) with or without biliary drainage. However, LC is a difficult procedure with higher documented morbidity than the transcystic approach. We retrospectively investigated risk factors for adverse outcomes of LC. METHODS We used logistic regression models ...

In this study, the manner of private taxis drivers has been investigated for choosing passenger and destination from a fixed point. Therefore, two models called Multinomial and Nested Logit Models have been utilized. The information gained by scrolling in 2016 is the input data, which are in the format of revealed preference, acquired by the verbal interview in Vanak Square in Tehran (Iran). Ba...

In this paper we combine recent advances in marginal modelling for contingency tables with the notion of copula to formulate a class of models for describing how the joint distribution of a set of ordinal response variables depends on exogenous regressors. We derive the main properties of a marginal parameterization, the global interaction copula, whose nature is essentially non parametric, and...

In this study, we propose two models for predicting people's activity. The first model is the pedestrian distribution prediction (or postdiction) model by multiple regression analysis using space syntax indices of urban fabric and people distribution data obtained from a field survey. The second model is a street choice model for visitors using multinomial logit model. We performed a questionna...

The purpose of this paper is to study the adoption of a new technology by a firm when the competitor comes into play at a random date that can be seen as her birth date. The presence of a competitor is thus only revealed when she invests. We show that there exists a unique Bayesian equilibrium that can be split into three stages. No firm will invest before a threshold T ∗ 1 even if she is born ...

A general phenomenon puzzles all investors is that on one hand, most individual investors believe they need to construct the portfolio consisting of 15 or more stocks to prevent risk because that large investment companies frequently get high returns is due to they obey the existing investment theory to make the portfolio consisting of more than 100 stocks, but the individual investors loss the...

Proximity is a fundamental concept in any comprehensive ontology of space (Worboys 2001). The provision of a context-contingent translation mechanism between linguistic proximity measures (e.g. “near”, “far”) and metric distance measures is an important topic in current GIS research. After a discussion of context factors that mediate the relationship between linguistic and metric distance measu...

This paper identifies several serious problems with the widespread use of ANOVAs for the analysis of categorical outcome variables such as forced-choice variables, question-answer accuracy, choice in production (e.g. in syntactic priming research), et cetera. I show that even after applying the arcsine-square-root transformation to proportional data, ANOVA can yield spurious results. I discuss ...

We study the maximum capture problem in facility location under random utility models, i.e., of seeking to locate new facilities a competitive market such that captured user demand is maximized, assuming each customer chooses among all available according maximization model. employ generalized extreme value (GEV) family discrete choice models and show objective function this context monotonic s...
