In this article, we propose generalized two-parameter (GTP) estimators and an algorithm for the estimation of shrinkage parameters to combat multicollinearity in multinomial logit regression model. addition, mean squared error properties are derived. A simulation study is conducted investigate performance proposed different sample sizes, degrees multicollinearity, number explanatory variables. ...

Background: Novel models for the assessment of non-linear data are being developed for the benefit of making better predictions from the data. Objective: To review traditional and modern models. Results, and Conclusions: 1) Logit and probit transformations are often successfully used to mimic a linear model. Logistic regression, Cox regression, Poisson regression, and Markow modeling are exampl...

The study analyzed farm households’ access and utilization of government health facilities in Kogi State, Nigeria. Specifically, it described the socioeconomic characteristics of farm households, determined the level of accessibility to health facilities by farm households, and determined the factors that drive farm households’ utilization of government health facilities. A two staged random sa...

In this paper estimators for distribution free heteroskedastic binary response models are proposed. The estimation procedures are based on relationships between distribution free models with a conditional median restriction and parametric models (such as Probit/Logit) exhibiting (multiplicative) heteroskedasticity. The first proposed estimator is based on the observational equivalence between t...

The noise levels measured in metropolitan streets are on many occasions over the norms but the consequences of this as a health hazard are only starting to be questioned; this is obviously worse in the large cities of the second and third worlds. A stated preference (SP) experiment was designed to estimate the willingness-to-pay (WTP) for reducing the noise level in a group based residential lo...

The rise of cell-only households (those in which a cell phone is the household’s only telephone service) has decreased the coverage of the landline telephone and may have introduced bias into landline survey samples. This paper considers ways in which cell-only and cell-mostly households may differ from the landline-only and landline-mostly populations thereby identifying factors which, when ad...

Recent studies have called into question the effectiveness of international human rights treaties. In this study I examine the variations in compliance that governments display concerning the Convention on the Elimination of all Forms of Discrimination Against Women (CEDAW). I argue that states will only keep their promises if the benefits of doing so outweigh the costs involved. In distinguish...

Little is known about bullying in rural areas.The participants in this study included 3,610 racially diverse youth (average age = 12.8) from 28 rural schools who completed the School Success Profile-Plus. Binary logistic regression models were created to predict bullying victimization in the past 12 months, and ordered logistic regression was used to predict school hassles in the past 12 months...

In this article, we estimate the price elasticities of demand for subscription and consumer switching costs for mobile telephony. We use a panel of Portuguese consumer level data to estimate a series of multinomial and mixed logit models. The demand for subscription is elastic. Switching costs are large. We use the structural model to perform several policy exercises. Switching costs and brand ...
