Work zones are critical parts of the transportation infrastructure renewal process consisting of rehabilitation of roadways, maintenance, and utility work. Given the specific nature of a work zone (complex arrangements of traffic control devices and signs, narrow lanes, duration) a number of crashes occur with varying severities involving different vehicle sizes. In this paper we attempt to inv...

Ekonominin stres dönemlerinin öngörülebilirliğinin makroekonomik göstergelerle belirlenmesi bu çalışmanın ana konusunu oluşturmaktadır. Bu amaçla Türkiye’nin 1996:01-2020:10 dönemi göstergeleri üzerinden spekülatif baskı endeksi oluşturulmuş ve Logit Probit olasılık modelleri kullanılarak ekonominin öncü tespit edilmeye çalışılmıştır. İncelenen dönemde endeksinin Ağustos 1998, Aralık 2000, Şuba...

In this paper we derive locally D-optimal designs for discrete choice experiments based on multinomial probit models. These models include several explanatory variables as well a quantitative one. The commonly used logit model assumes independent utilities different options. Thus, optimal such may comprise sets, e.g., consisting of alternatives which are identical in all attributes but the vari...

The main feature of the CoIL challenge data is that the observed response is discrete: we only observe whether or not the customers buy caravan insurance. Models for such data were developed in the 1940s and 1950s in the Bio-statistics literature (see references in Cox and Snell, 1989), in particular LOGIT and PROBIT. In the 1970s such techniques became popular in Economics, where a utility max...

A growing number of empirical studies involve the assessment of influences on a choice amongst ordered discrete alternatives. Ordered logit and probit models are well known, including extensions to accommodate random parameters and heteroscedasticity in unobserved variance. This paper extends the ordered choice random parameter model to permit random parameterization of thresholds and decomposi...

In this paper we investigate whether technical efficiency is an important ex-ante predictor of business failure. We use samples of French textiles, wood, and R&D companies to obtain efficiency estimates for individual firms in each industry. These efficiency measures are derived from a directional technology distance function constructed empirically using non-parametric Data Envelopment Analysi...

Abstract In this paper we provide an overview of the patterns of intergenerational proximity and coresidence of adult children and their mothers in the U.S., using data from the National Survey of Families and Households (NSFH) and the U.S. Census. We highlight the importance of three specification and sample choices in the analysis. First, most previous studies consider coresidence to be the l...
