A Bayesian hierarchical model for correlation in microarray studies
Microarrays are miniaturised biological devices consisting of molecules (e.g. DNA or protein), called \probes", that are orderly arranged at a microscopic scale onto a solid support such as a nylon membrane or a glass ... -
A copula-based approach to differential gene expression analysis
Melanoma is a major public health concern in the developed world. Melanoma research has been enhanced by the introduction of microarray technology, whose main aim is to identify genes that are associated with outcomes ... -
A Phase transition in the distribution of the length of integer partitions
We assign a uniform probability to the set consisting of partitions of a positive integer n such that the multiplicity of each summand is less than a given number d and we study the limiting distribution of the number of ... -
A smooth test of goodness-of-fit for the baseline hazard function in recurrent event models
In this paper, we formulate a smooth test of goodness-of-fit for a simple hypothesis about the baseline hazard function in recurrent-event models. The formulation is an extension of Neyman' s goodness-of-fit approach, ... -
Adverse information on social media will always send Kenyans to withdraw their money
(2016-04)In the paper “The Extent to Which Social Media Can Influence a Bank Run” Atieno,T. and Mutinda, M. (2014) provided empirical evidence that there was a huge risk of a bank run occurring in Kenya due to social media. This ... -
Conditional CAPM in financial risk management: a quantile autoregression approach
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 ... -
Devolution and nation building
One of the key reforms of the constitution is the establishment of devolution through the country’s government. It is in the current constitution and will only come into effect after the next general elections, when the ... -
Extending genstat capability to analyze rainfall data using Markov chain model
Rainfall is of critical importance for many people particularly those whose livelihoods are dependent on rain fed agriculture. Methods of analysis of daily rainfall records based on Markov chain models have been available ... -
Laguerre Polynomials and singular differential operators
This paper is concerned with the connections between the orthogonal polynomials and the differential operators generated by the Laguerre differential equation of Ten in the space L' (0, w ). However, for the left definite ... -
Managing chronic conditions through hosted medical records in Kenya
Complex medical conditions are rising in developing countries at very alarming rates. E.g. projections from the World Health Organization’s global burden of disease and risk factors report chronic diseases are responsible ... -
Mathematical model for HIV and CD4+ cells dynamics in vivo
Mathematical models are used to provide insights into the mechanisms and dynamics of the progression of viral infection in vivo. Untangling the dynamics between HIV and CD4+ cellular populations and molecular interactions ... -
Mathematical Modeling for Human Immunodeficiency Virus (HIV) Transmission using Generating Function Approach
(Strathmore university, 2009)This study is concerned with the mathematical modeling for human immunodeficiency virus (HIV) transmission epidemics. The mathematical models are specified by stochastic differential equations that are solved by use of ... -
Model-Assisted Estimation of Finite Population Mean in Two-stage Cluster Sampling
Estimation of finite population parameters has been an area of concern to statisticians for decades. This paper presents an estimation of the population mean under a model-assisted approach.Dorfman (1992), Breidt and Opsomer ...
