Fitting Time-series Models to Kisumu Rainfall Data for the Period 1961-2014
(Science Publishing Group, 2020-02-20)Many small-scale farmers require adequate forecasts to help them plan for the rainfall. The National Meteorological Service provides forecasts seasonally, monthly and weekly. The forecasts are qualitative in nature hence ... -
Fitting Wind Speed to a Two Parameter Distribution Model Using Maximum Likelihood Estimation Method
(Science Publishing Group, 2020)Kenya is among the countries that are continuously investing in wind energy to meet her electricity demand. Kenya is working towards its vision 2030 of achieving a total of 2GW of energy from wind industry. To achieve ... -
Inference Properties of QIC in the Selection of Covariates for Generalized Estimating Equations
(HIKARI Ltd, 2019)The Quasi-likelihood information criterion (QIC)which results from utilizing Kullbacks I-divergence as the targeted discrepancy is widely used in the GEE framework to select the best correlation structure and the best ... -
International Journal of Mathematical Archive-2 (10), 2011, Page: 2027-2029 Available online through www. ijma. info ISSN 2229–5046
(IJMA, 2011)In this paper, the age-structured population matrix, also known as Leslie matrix, has been extended to model the dynamics of migrating individuals. Aggregation techniques have been used to estimate the parameters of the ... -
Jumps in the Kenyan Interest Rates
(INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY SCIENCES AND ENGINEERING, 2014-11-11)— In this paper, we use the Bernoulli Jump Diffusion (BJD) process to test for the existence and probability of jumps in the Kenyan interest rates. We test these using the Maximum Likelihood Estimation (MLE) method on ... -
Logistic Regression on Effects of Relationship Between Condom Use on Comprehensive HIV Knowledge Among the Youths in Kenya
(Science Publishing Group, 2019-09-13)HIV/AIDS knowledge in Kenya is universal in that 99% of both male and female have heard of the epidemic and how it can be avoided. Despite the widespread knowledge of HIV/AIDS, comprehensive HIV knowledge which refers to ... -
Markovian Approach for Analyzing Patient Flow Data: A Study of Kapsabet County Referral Hospital, Kenya
(science publishing group, 2022)Hospital is indispensable and necessary welfare of society. Through it, we can manage our illnesses by treatment and prevention interventions. With the rise incidences of chronic diseases and illnesses, there has been an ... -
Modeling of jumps and mean reversion in the Kenyan interest rates

Modeling trailer-traffic flow on a Kenyan highway
(2014)Traffic flow modelling is studied in order to ease congestion on roads. However, congestion is also caused by irregular occurrences, such as traffic accidents, poor roads, vehicle disablement, spilled loads and hazardous ... -
Modelling of distribution of the “Matatu” traffic flow using Poisson distribution in a highway in Kenya
(HIKARI Ltd, 2018)Traffic congestion in urban road and freeway networks leads to strong degradation of the network infrastructure and accordingly reduced output. Expansion of the available transportation continues to be one of the solution ... -
On (P, Q)-Binomial Extension of Cox-Ross-Rubinstein Model in Skorohod Spaces.
(International Journal of Open Problems in Computer Science & Mathematics, 2023-12-01)In this paper, we develope a (pq)-binomial extension of the Cox-Ross-Rubinstein (CRR) model thereby enhancing its ap plicability in optimizing life insurance portfolios amidst noisy observations. We utilize mathematical ... -
On the Theory of Random Search
(University of Nairobi,, 1994)The problem of identifying one or more unknown elements belonging to a finite set So' containing n distinguishable elements is well known in literature. Designs used in this kind of investigation are known as search designs. ... -
Option Pricing of an Asset with Seasonal and Periodic Supply
(International Journal of Multidisciplinary Sciences and Engineering, 2014-12-12)In option pricing the rate of change of asset price with time can be viewed to be directly proportional to the Walrasian [6] excess demand. Scholars such as Jacques [3] and Onyango [4], have used the excess demand concept ... -

Portfolio optimization for extended (p, q) –binomial cox –ross- rubinstein model
(SSAR Publishers, 2024-03-11)In this paper, we focus on establishing optimization conditions for the extended binomial Cox-Ross-Rubinstein (CRR)model, particularly in the context of managing portfolios in life insurance under varying noise conditions. ... -
Recursive Relation for Zero Inflated Poisson Mixture Distributions
(HIKARI Ltd, 2017)The paper extends the work of Sarguta who derived recursive re lations for univariate distributions by considering the ZIP continuous mixtures. The paper gives a recursive formular which can be used to evaluate the mixed ... -
Spatial Comparison and Quality Check of Farmer-recorded Daily Rainfall Data; A Case of Nyakach and Soin-sigowett, Kenya
(Science Publishing Group, 2020-01-09)Small scale farming is currently still heavily dependent on rainfall in developing nations. With the challenge of climate change, many innovations are proposed to help the farmers mitigate and adapt. The use of historical ... -
