This article focuses on the estimation of population proportion when the study variable is sensitive in nature. Two implicit randomized response techniques are proposed where the unrelated trait can be chosen subjectively. In addition to unbiased estimation of population proportion and variance, an empirical study is conducted to inspect the relative efficiency facet of the proposed techniques....

A Poisson model typically is assumed for count data, but when there are so many zeroes in the response variable, because of overdispersion, a negative binomial regression is suggested as a count regression instead of Poisson regression. In this paper, a zero-inflated negative binomial regression model with right truncation count data was developed. In this model, we considered a response variab...

We present BTE-Barna (Boltzmann Transport Equation - Beyond the Rta for NAnosystems), a software package that extends Monte Carlo (MC) module of almaBTE solver Peierls-Boltzmann transport equation phonons (PBTE) to work with nanosystems based on 2D materials complex geometries. To properly capture how phonon occupations evolve in momentum space as result scattering, we have supplemented relaxat...

In some data envelopment analysis (DEA) applications, some inputs of DMUs have negative values with positive cost. This paper generalizes the global cost Malmquist productivity index to compare the productivity of dierent DMUs with negative inputs in any two periods of times under variable returns to scale (VRS) technology, and then the generalized index is decomposed to several components. The...

introduction: child mortality indices are key element that reflects health status of societies and inform policy makers to take suitable policies to reduce them. this study was performed to examine the main determinants of under-5 mortality rate (u5mr) in oecd countries in two cross-sections, 2010 and 2013, and the results of them was compared. material and methods: this was a cross- sectional ...

the purpose of follow study concerned review of relation between extraversion, consciousness, negative and positive affect risky driving behavior. the population of this study is involved whole men driver in tehran and divided in two groups including: 202 men with risky driving behavior and 192 men without risky driving behavior. they are selected by random sampling method. gordon five factor q...
