CLASSIFICATION RATES: NON-PARAMETRIC VERSES PARAMETRIC MODELS USING BINARY DATA
(Journal of Agriculture, Science and Technology, 2014)Estimations of the conditional mean and the marginal effects for particular small changes in the covariates have been of interest in financial, economics and even educational sectors. The standard approach has been to ... -
Comparing Edgeworth Expansion and Saddlepoint Approximation in Assessing the Asymptotic Normality Behavior of A Non-Parametric Estimator for Finite Population Total
(EJ-MATH, European Journal of Mathematics and Statistics, 2023-01)Abstract — Sample surveys concern themselves with drawing inferences about the population based on sample statistics. We assess the asymptotic normality behavior of a proposed nonparametric estimator for finite a population ... -
Comparison of some Panel Data Regression Model Estimators using Simulated Data
(JKUAT, 2016)This paper presents estimation of panel data regression models with individual effects. We discuss estimation techniques for both fixed and random effects panel data regression models. We derive two-stage least squares and ... -
Comparison of the ratio estimate to the local linear polynomial estimate of finite population totals
(International Journals of Multidisciplinary Research Academy, 2013)In this paper, attempt to study effects of extreme observations on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate ... -
Control of the polarization direction of isolated attosecond pulses using inhomogeneous two-color fields
(Nature Publishing Group, 2019)We theoretically demonstrate the control of the polarization direction of isolated attosecond pulses (IAPs) with inhomogeneous two-color fields synthesized by an 800-nm fundamental pulse and a 2000- nm control pulse having ... -
Coverage properties of a neural network estimator of finite population total in high-dimensional space.
(Journal of Mathematics, 2022)The problem in nonparametric estimation of finite population total particularly when dealing with high-dimensional datasets is addressed in this paper. The coverage properties of a robust finite population total estimator ... -
The Cube Duplication Solution (A Compass-straightedge (Ruler) Construction)
(International Journal of Mathematics Trends and Technology, 2017)This paper objectively presents a provable construction of generating a length of magnitude;, as the geometrical solution for the ancient classical problem of doubling the volume of a cube. Cube duplication is believed to ... -
Deep Learning Incorporated Bu¨hlmann Credibility in the Modified Lee–Carter Mortality Model
(Hindawi, 2023-03)This research study proposes the inclusion of randomness or an error term in the modified Lee–Carter model, which improves the traditional Lee–Carter model for modeling and forecasting mortality risk for years in the ... -
Defect-induced room temperature ferromagnetic properties of the Al-doped and undoped ZnO rod-like nanostructure
(Elsevier, 2017)In this work, electron paramagnetic resonance (EPR) experiment on undoped ZnO and Al doped ZnO (AZO) nanoparticles prepared by facile sol–gel method were investigated. The effects of the Al concentration on room temperature ... -
Deriving Penalized Splines For Estimation Of Time Varying Effects In Survival Data
(International Journal of Scientific & Technology Research, 2014)The major interests of survival analysis are either to compare the failure time distribution function or to assess the effects of covariate on survival via appropriate hazards regression models. Cox’s proportional hazards ... -

A Deterministic Model Of HIV Transmission Between Two Closed Patches Incorporating The Monod Equation
(International Institute for Science, Technology and Education (IISTE), 2019-06)Among other factors, migration has significantly contributed to the spread of HIV. Recent studies have revealed that new infections occur along major transport corridors and truck-drivers have overall higher prevalence ... -
Dicarbonyl (hexamethylene-1, 3, 5, 7-tetramine-κN1)(η5-pentamethylcyclopentadienyl) iron (II) tetrafluoridoborate
(International Union of Crystallography, 2012)In the title compound, [Fe(C10H15)(C6H12N4)(CO)2]BF4, the arrangement around the FeIIatom corresponds to a three-legged piano stool. The pentamethylcyclopentadienyl (Cp*) ligand occupies three coordination ... -

(International Union of Crystallography, 2012)In the structure of the title compound, [Fe(C5H5)(C6H12N4)-(CO)2]BF4, the arrangement around the FeIIatom corresponds to that of a three-legged piano stool. The cyclopenta-dienyl ligand occupies three coordination sites ... -
Diversity and Altitudinal Distribution of Understorey Corticolous Lichens in a Tropical Montane Forest in Kenya (East Africa).
(ResearchGate, 2017)Lichens constitute an important component of tropical forest biodiversity. This study inventoried corticolous lichens and examined their variation in various forest types with varying climatic conditions in Mt. Kenya, ... -
E-2-hexenal promotes susceptibility to Pseudomonas syringae by activating jasmonic acid pathways in Arabidopsis
(Frontiers in Plant Science, 2013-04)Green leaf volatiles (GLVs) are C6-molecules – alcohols, aldehydes, and esters – produced by plants upon herbivory or during pathogen infection. Exposure to this blend of volatiles induces defense-related responses in ... -
Effect of Mn doping on the structural and optical properties of sol-gel derived ZnO nanoparticles.
(Springer, 2011)Un-doped and Mn-doped ZnO nanoparticles were successfully synthesized in an ethanolic solution by using a sol-gel method. Material properties of the samples dependence on preparation conditions and Mn concentrations were ... -
