(University of Nairobi, 2016)The transition from web 1.0 to web 2.0 has enabled direct interaction between users and its environment such as social media networks. In this research paper we have analyzed algorithms for sentiment analysis which can be ... -
A comparative verification of precipitation forecasts for selected numerical weather prediction models over Kenya
(Department of Meteorology University of Nairobi, 2006)This study examined the level of skill of daily precipitation forecasts of Numerical Weather Prediction (NWP) models over Kenya. These models are the United Kingdom Meteorological office (UKMO) model, United States' ... -
Comparing Accelerated Failure Time and Cox Ph Models:a Case Study on Employee Attrition
(University of Nairobi, 2022)The goal of this project, is to compare the AFT model and Cox PH model using the employee attrition data set. Survival analysis examines the desired outcome until the occurrence of the event. Although Cox PH together ... -
Comparing different Classification Algorithms to predict the Adherence to Tuberculosis Treatment for new cases in Kenya
(University of Nairobi, 2020)This study determines factors that are associated to non-adherence to tuberculosis treatment in Kenya. In the African Region, over 25% of the tuberculosis deaths occur. Kenya is among the 30 high burden countries accounting ... -

(Department of Zoology, University of Nairobi, 2006)Schistosomal vaccine candidates such as Paramyosin and Multiple antigen epitopes (MAP) are in different stages of development and clinical trials. However, it is probable that during initial field clinical trials, some ... -
Comparison Between Lee-Carter Model And Negative Binomial Regression Model In Forecasting Male Mortality Data Of Usa(1980-2020)
(University of Nairobi, 2018)People living in America today are living longer compared to yester years; this is due to reduced mortality rates and increase in life expectancy. According to (Dye & Williams, 2010) generally mortality rates have ... -
Comparison Between Two Simple Linear Catchment Models For The Yala River Basin
(Department of Meteorology, 1987)In this study, two simple linear catchment models were used to model the rainfall-runoff characteristics over Yala catchment. The first model was based on the response function. In this model a linear stochastic process ... -
