This paper develops a threshold regression model where an unknown relationship between two variables nonparametrically determines the threshold. We allow observations to be cross-sectionally dependent so that can applied determine spatial border for sample splitting over random field. derive uniform rate of convergence and nonstandard limiting distribution nonparametric estimator. also obtain r...

background: municipal solid waste (msw) is the natural result of human activities. msw generation modeling is of prime im­portance in designing and programming municipal solid waste management system. this study tests the short-term pre­diction of waste generation by artificial neural network (ann) and principal component-regression analysis. methods: two forecasting techniques are presented in...

in this research, a new control policy for the acceptance sampling problem is introduced. decision is made based on the number of defectives items in an inspected batch. the objective of the model is to find a constant control level that minimizes the total costs, including the cost of rejecting the batch, the cost of inspection and the cost of defective items. the optimization is performed by ...

in this research genetic and phenotypic parameters were estimated using linear and threshold models, for reproductive traits, data from 6 large industrial dairy herd of east azerbaijan province collected by agriculture jihad organization during 10 years (2001-2010). best linear unbiased predictions of traits breeding values were estimated using restricted maximum likelihood method by wombat sof...

Using different combinations of culture, development and openness to international trade, we test the variability in the incidences of corruption at different stages of development or in other words the non-linearities in the relationship between corruption and development. We employ formal threshold model developed by Hansen (2000), and unlike the existing literature, we find that: (1) non-lin...

regarding the important role of health in economic growth and development, the purpose of the present paper is to investigate the impact of life expectancy, as the most important indicator of health, on economic growth in iran during 1965-2009. the estimated smooth transition regression (str) model supports a nonlinear threshold behavior in the relationship between life expectancy and economic ...

This paper investigates the nonlinear relationship between capital structure and firm performance in MENA region using a sample of 499 listed firms over 2007–2020 period, or 6986 firm-year observations. Specifically, we examine size-threshold effect structure–firm nexus. To do so, this study applies dynamic panel threshold regression model (DPTR). The findings show that there is debt (Tobin’s Q...
