Binomial Mixtures Based on Beta I Distribution and Its Generalizations with Application to a Two Stage Group Screening Design
(Bulletin of Mathematics and Statistics Research, 2018)When mixed, two distributions can form another distribution. Binomial distribution and beta distributions combine to form a binomial mixture with the latter being a prior distribution which is a continuous distribution. ... -
Application of Three Parameter Generalized Beta I Distribution in Binomial Mixture
(Bulletin of Mathematics and Statistics Research, 2018)Two or more individual distributions can be mixed together to form a new distribution. According to Feller, this can be done using weights that sum up to unit. Also by considering a parameter which is a random variable ... -

Aflatoxin B1 Affects Kenyan Markets: How It Can be Managed
(Advances in Research, 2020-02-14)Aflatoxin B1 is a toxin produced as secondary fungal metabolites by the fungus Aspergillus, particularly A. flavus. The toxin has significantly contaminated the food supply chain especially cereals in Kenya. Kenya Bureau ... -
Gametocytemia and Attractiveness of Plasmodium falciparum–Infected Kenyan Children to Anopheles gambiae Mosquitoes
(The Journal of Infectious Diseases, 2017-06-13)It has been suggested that Plasmodia manipulate their vertebrate hosts to enhance parasite transmission. Using a dual-choice olfactometer, we investigated the attraction of Anopheles gambiae to 50 Kenyan children (aged ... -
Optimal Allocation in Small Area Mean Estimation Using Stratified Sampling in the Presence of Non-Response
(International Journal of Statistical Distributions and Applications, 3/12/2021)Sample survey provides reliable current statistics for large areas or sub-population (domains) with large sample sizes. There is a growing demand for reliable small area statistics, however, the sample sizes are too small ... -
Economic Value of Non-Timber Forest Products Utilized by The Households Adjacent to the South Nandi Forest Reserve in Kenya
(Taylor & Francis Online, 2019-10-30)Many rural dwellers in tropical regions depend on non-timber forest products (NTFPs) for their livelihood and income requirements. However, the link between the economic benefits of NTFPs and their resource base (including ... -
Land Use Changes and Impacts on Livelihoods of the Communities Adjacent to Mt Elgon Forest Ecosystem
(Journal of Geography, Environment and Earth Science International, 2020-09-28)Forests play a critical role in providing essential goods and services to forest adjacent communities. There is, however, insufficient information on how land uses affect the availability and use of forest products and ... -
Assets Valuation Using a Contingent Claim
(International Journal of Science and Research (IJSR), 2017-02)In this paper we consider the price dynamics of a portfolio consisting of risk-free and risky assets. The paper discusses the pricing process of a contingent claim, the pricing equation and the risk-neutral valuation under ... -
Logistic Black-Scholes-Merton Partial Differential Equation: A Case of Stochastic Volatility
(International Journal of Scientific Engineering and Research (IJSER), 2018)Real world systems have been created using differential equations, this has made it possible to predict future trends and behaviour. Specifically, stochastic differential equations have been fundamental in describing and ... -
Invasive Species Population Status Modeling Using Stage Based Matrix: Mount Elgon Ecosystem
(Mathematical Theory and Modeling, 2019)The matrix models have been applied to evaluate the impacts and management of tree species. Modeling of invasive species using stage based matrix methods has not been exploited to understand the population structure of the ... -
Metacognitive Monitoring as Predictor of Mathematics Achievement among Students in Public Secondary Schools in Kenya
(International Journal of Psychology and Behavioral Sciences, 2019)This study investigated metacognitive monitoring as a predictor of mathematics achievement among students in public secondary schools in Kisii Central Sub County, Kenya. The study was guided by the Social Development Theory ... -
Optimal Allocation in Double Sampling for Stratification in the Presence of Nonresponse and Measurement Errors
(International Journal of Statistics and Applied Mathematics, 2019)The present study addresses the problem of minimum cost and precision in the estimation of the population mean in the presence of nonresponse and measurement errors. It is assumed that both the survey variable and the ... -
Relationship between Goal-Setting and Mathematics Achievement among Students in Public Secondary Schools in Kenya
(International Journal of Advanced and Multidisciplinary Social Science, 2019)The purpose of this study was to investigate selected goal-setting as a predictor of mathematics performance among students in public secondary schools in Kisii Central Sub-County, Kenya. The study was guided by the Social ... -
Probability of Default Estimation for Commercial Lenders in Developing Economies: Creditworthiness of Consumer Borrower
(Global Scientific Journals, 2019-06)The Business of advancing credits is gradually becoming a major target for many banks, as a result there is high competition among the financial institutions leading to default of most credits. In order to raise the quality ... -
Knockdown of Ghalba_4 and Ghalba_5 Proteins in Cotton Inhibits Root Growth and Increases Sensitivity to Drought and Salt Stresses
