    • On the Theory of Random Search 

      FREDRICK BERNARD ODHIAMBO ORYARGO (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 

      Apaka Rangita (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 ...
    • Option Pricing of an Asset with Seasonal and Periodic Supply 

      Option Pricing of an Asset with Seasonal and Periodic Supply (International Journal of Multidisciplinary Sciences and Engineering, 2014)
      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 ...
    • Recursive Relation for Zero Inflated Poisson Mixture Distributions 

      Anyango, L. Cynthia, Edgar Otumba (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 

      Mawora Thomas Mwakudisa, Edgar Ouko Otumba, Joyce Akinyi Otieno (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 ...
    • Statistical trend analysis of residential water demand in Kisumu City, Kenya 

      Robert Nyamao Nyabwanga, Edgar Ouko Otumba, Fredrick Onyango, Simeyo Otieno (Science Publishing Group, 2015-04-16)
      This study sought to analyse trend in the monthly water demand data series in Kisumu city at both seasonal and non-seasonal levels using the parametric method of Ordinary Least Squares (OLS) and non-parametric methods of ...
    • Supply, Demand, Equilibrium, Deterministic, Stochastic, Logistic and Differential Equations 

      Apaka Rangita, Silas N Onyango, Omolo Ongati, Otula Nyakinda (INTERNATIONAL JOURNAL OF MULTIDISCIPLINARY SCIENCES AND ENGINEERING, 2014)
      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 the ...
    • Temperature Distribution for Magnetohydrodynamic Flow in Straight Horizontal Elliptical Pipe 

      David Kweyu, J Bitok, W Manyonge (Applied Mathematical Sciences, 2021)
      A study has been carried out on temperature distribution on Magnetohydrodynamic (MHD) fluid flow in a pipe of elliptical cross section. Fluid is electrically conducting, viscous and incompressible. Governing equations are ...
    • Training of lecturers at Maseno University, Kenya 

      James Musyoka, Joyce Otieno, David Stern (Proceedings of the ICOTS8 conference, 2010)
      Lecturers in Kenyan universities usually start their work without any prior training on how to teach students. Hence the teaching tends to be traditional and new training techniques are rarely implemented. For effective ...
    • Using e-learning to engage Mathematics and Statistics Students in a Kenyan University 

      JK Musyoka, D Stern, J Otieno (12th International Congress on Mathematical Education, 2012)
      Two introductory courses to statistics were taught to first year mathematics and statistics students as part of an initiative to introduce them to computers. The courses were offered using a blended approach which included ...
    • Zero Inflated Poisson Mixture Distributions 

      Cynthia L Anyango, Edgar Otumba, John M Kihoro (Applied Mathematical Sciences, 2017)
      This paper presents a method of constructing the Zero inflated Poisson continuous mixture distributions which have applications in various fields. The distributions can be formed by either direct integration or integration ...
