Conflict resolution using statistical approach
(Academic Journals, 2010)Conflict can be described as a condition in which actions of one person prevent or compel some outcome at the resistance of the other. Quite often this can be seen as “two or more competing, often incompatible, responses ... -
Challenges Affecting Implementation of Strategic Plan in Kenya Health Sector; A Case of Public Hospitals in Machakaos County
(Noble Academic Publisher, 2017)Strategic planning and its implementation in Kenya at the Ministry of Health is an element of the on-going public sector reforms designed to improve the delivery of health care services. However, this implementation has ... -
Influence of employee resourcing on organizational performance of devolved governments in South Eastern Kenya region
(2019)The study focused on the influence of human capital factors on performance of devolved Governments in South Eastern Kenya region. The specific objective of the study being to establish the influence of employee resourcing ... -
Assessment of corporate management practices in public universities in Kenya
(Academic Journals, 2013)In order to continue attracting and retaining high-class intellectual power and hence guarantee quality service delivery, public university management will need to change and adjust in line with increasing local ... -
General Circulation Models (GCMs) Downscaling Techniques and Uncertainty Modeling for Climate Change Impact Assessment
(Proceedings of 2013 Mechanical Engineering Conference on Sustainable Research and Innovation, 2013)Scientific literature on the assessment and projection of climate change impacts suggests that the rapidly changing climate conditions are causing far-reaching consequences on natural resources and agricultural production. ... -
SWAT model parameter calibration and uncertainty analysis using the HydroPSO R package in Nzoia Basin, Kenya
(Journal of Sustainable Research in Engineering, 2014)The parameter uncertainty in hydrological modelling has been accorded much attention in the recent past.Parameter uncertainty is a major source of overall model unreliability. In this study, the HydroPSO R package was used ... -
Spatio-temporal vegetation dynamics and relationshipwithclimate over East Africa
(Hydrol. Earth Syst. Sci. Discuss, 2016)Vegetation plays a key role in the global climate system via modification of the water and energy balance. Its coupling to climate is therefore important particularly in the tropics, where severe climate change impacts ... -
Estimation of T- period’s ahead extreme quantile autoregression function
(African Journal of Mathematics and Computer Science Research, 2010)This paper considers the estimation of extreme quantile autoregression function by using a parametric model. We combine direct estimation of quantiles in the middle region with that of extreme parts using the model and ... -
A Three-Step Nonparametric Estimation of Conditional Value-At-Risk Admitting a Location-Scale Model
(Journal of Statistical and Econometric Methods, 2019)Financial institutions owners and regulators are concerned majorly about risk analysis, Value-at-Risk (VaR) is one of the most popular and common measures of risk used in finance, measures the down-side risk and is ... -
Conditional scale function estimate in the presence of unknown conditional quantile function
(African Network of Scientific and Technical Institutions (ANSTI), 2005)Standard approach for modeling and understanding the variability of statistical data or, generally, dependant data, is often based on the mean variance regression models. However, the assumptions employed on standardized ... -
Prediction of the Likelihood of Households Food Security in the Lake Victoria Region of Kenya
(2011)This paper considers the modeling and prediction of households food security status using a sample of households in the Lake Victoria region of Kenya. A priori expected food security factors and their measurements are ... -
Nonparametric Estimates for Conditional Quantiles of Time Series
(2014)We consider the problem of estimating the conditional quantile of a time series fYtg at time t given covariates Xt , where Xt can either exogenous variables or lagged variables of Yt . The conditional quantile is ... -
Nonparametric Mixed Ratio Estimator for a Finite Population Total in Stratified Sampling
(2018)We propose a nonparametric regression approach to the estimation of a finite population total in model based frameworks in the case of stratified sampling. Similar work has been done, by Nadaraya and Watson (1964), Hansen ... -
Expression Characteristics of CS-ACS1, CS-ACS2 and CS-ACS3, ThreeMembers of the 1-AminocycIopropane-l-Carboxylate Synthase Gene Familyin Cucumber {Cucumis sativus L.) Fruit under Carbon Dioxide Stress
(1999)We investigated the expression pattern of three 1-aminocydopropane-1-carboxylate (ACC) synthase genes,CS-ACS1, CS-ACS2 and CS-ACS3 in cucumber (Cucumissativus L.) fruit under CO2 stress. CO2 ... -
Distributive and Quantile Treatment Effects: Imputation Based Estimators Approach
(Journal of Statistical and Econometric Methods, 2018)This paper develops two new classes of estimators measuring the distributive effects of a treatment on a population. Using imputation methods, empirical quantile and bootstrap simulations, we managed to define and study ... -
Bootstrap Uniform Confidence Bands for A Local Linear Nonparametric Estimator and Applications to Financial Risk Management
(2012)This paper considers the problem of bootstrapping a local linear estimator in conditional quantile estimation of a financial time series assuming independent and identically distributed errors. A nonparametric ... -
Conditional CAPM in Financial Risk Management: A Quantile Autoregression approach
(2012)The study aims to provide a comprehensive description of dependence pattern of a stock by studying a range of betas derived as quantiles of conditional return distribution using quantile regression based on moving window ... -
Effects of malting and fermentation treatments on group B-vitamins of red sorghum, white sorghum and pearl millets in Kenya
(Journal of Applied Biosciences, 2010)Objectives: To enhance the safety and nutritive values and shelf life of sorghums and millet flours through malting and fermentation. Methodology and results: Malting and fermentation were carried out for a period of seven ... -
Modelling the volatility of exchange rates in the Kenyan market
(Academic Journals, 2010)This paper considers the application of the generalized autoregressive conditional heteroscedasticity process in the estimation of volatility in the Kenyan exchange rates. A quasi-maximum likelihood estimation procedure ... -
Using Conditional Extreme Value Theory to Estimate Value-at-Risk for Daily Currency Exchange Rates
(IOP Publishing, 2017)This paper implements different approaches used to compute the one-day Value-at-Risk (VaR) forecast for a portfolio of four currency exchange rates. The concepts and techniques of the conventional methods considered in ...
