We propose a semiparametric estimator for multinomial discrete choice models. The term “semiparametric” refers to the fact that we do not specify a particular functional form for the error term in the random utility function and we allow for heteroskedasticity and serial correlation. Despite being semiparametric, the rate of convergence of the smoothed maximum score estimator is not affected by...

We introduce methods for estimating a Bayesian multinomial probit switching model for unordered selection and response categories via a fully Gibbsian estimation strategy. We achieve this through the use of marginal data augmentation and a modified Imai/van Dyk-type prior for the covariance matrix. Compared to related work that requires a Metropolis step, this method improves computational effi...

this paper discusses the study of community’s preferences for biodiversity conservation management institution which may motivate them to support conservation efforts in the okwangwo division of the cross river national park, nigeria. the empirical data was generated from personal interviews and factors influencing the respondents’ choice were examined with the aid of multinomial logit mode...

background and aims: aspergillus fumigatus is a sporadic fungus that causes different infections and allergies in immunocompromised patients. the allergic disease caused by this fungus is called allergic bronchopulmonary aspergillosis (abpa). abpa is considred important in atopic and immunocompromised individuals, which can result in inflammation and epithelial damage. therefore, the aim of thi...

objective: social anxiety disorder (sad) is defined as a constant fear of being embarrassed or negatively evaluated in social situations or while doing activities in the presence of others. several studies have examined the role of certain variables that might predict response to treatment and may affect treatment outcome. the purpose of this study was to identify predictive variables of change...

Introduction: Substantive amount of work has been done in modeling and analyzing the scintillation camera system processes including positioning and image formation. The goal of this work is to develop a framework for analyzing performance of nonlinear positioning methods upon construction of a mathematical model of the system. In this study, the photodetector array counts are ...
