Analysis of recurrent events with associated informative censoring: application to HIV data
(Strathmore University, 2020-06)In this study, we adapt a commonly used Cox-based model for recurrent events; the Prentice, Williams and Peterson Total -Time (PWP-TT) that has been largely used under the assumption of non-informative censoring and evaluate ... -
Assessing efficient odds ratios: an application to surgical stage prediction in cervical cancer
(Strathmore University, 2020)Background: Cervical cancer remains the second most commonly diagnosed cancer and the third leading cause of cancer death in developing countries. Improving clinicians' knowledge and understanding of surgical staging is ... -
A Bayesian approach to Geo spatial analysis of HIV viral load data
(Strathmore University, 2019)HIV is currently ranked among the leading causes of death in Kenya and in the world, with an estimated 1.5 Million Kenyans living with HIV and 28,000 deaths recorded annually as a result of AIDS related illnesses. In 2014, ... -
Classification of X-rays images using Deep Convolutional Neural Network: COVID-19
(Strathmore University, 2021)The increased amount of labeled X-ray image archives has triggered increased research work in the application of statistics, machine learning, deep learning, and computer vision across the different domains. The fresh ... -
Determine the breaking point of Kenya debt an application of extreme value theory
(Strathmore University, 2017)The aim of the study is to determine the breaking point of Kenyan public debt through the use of Extreme Value Theorem (EVT). EVT focuses on the tail end of distributions to be able to identify maxima and minima points. ... -
Developing pediatric prognostic model using finite mixture models
(Strathmore University, 2017)Background: World Health Organization (WHO) guidelines recommend early identification of patients who have emergency features for early medical intervention with the aim of reducing child mortality and morbidity. Prognostic ... -
Distributions of zero-inflated models with application to HIV exposed infants
(Strathmore University, 2019)The instances of data with excess zeros are commonly found in many disciplines, including the public health. Several models have been proposed when analyzing this kind of data. The World Health Organization (WHO) indicates ... -
Forecasting Kenya’s GDP using a hybrid neural network and ARIMA model
(Strathmore University, 2020-03)Background: Gross Domestic Product (GDP) is the market value of goods and services produced within a selected geographical area usually a coun- try in a selected interval in time often a year and can be measured ... -
Forecasting of the inflation rates in Kenya: a comparison of ANN, ARIMA and SARIMA
(Strathmore University, 2021)Monetary policies like price stability are regulated by the Central Bank of Kenya (CBK). Price stability is a key indicator of stable and predictable inflation. Accuracy and reliability in forecasting the inflation rates ... -
Identifying the best method to correct for missing data, a case of HIV/TB co-infection in Kenya
(Strathmore University, 2020)Having missing information is almost inevitable in research, but many researchers only report on complete cases. Here we review the missing data theory, missingness characteristics, look at the background information, ... -
A Joint modelling approach of monthly anthropometry and time to death among hospitalized severe malnourished children in Kenya
(Strathmore University, 2021)Background: In follow up studies, interest often lies in understanding the association between biomarkers measured over time and a time-to-event outcome. For this, a two-stage separate analysis or the use of time-dependent ... -
Modelling the structure of dependence of stock markets in BRICS & KENYA: Copula GARCH approach
(Strathmore University, 2017)Background: Dependence structure is used widely to describe relationships between risks and provides estimation of risks for risk management purposes. Modeling dependence structure of stock returns is a difficult task ... -
Predictive modeling of Logistics Performance Index using Sparse Regression Models
(Strathmore University, 2021)The Logistics Performance Index (LPI), developed by The World Bank, is the only interactive benchmarking tool countries use to identify challenges and opportunities in trade logistics. It was developed using Principal ... -
Predictive modelling in credit risk: a survival analysis case
(Strathmore University, 2017)Six survival analysis techniques are accessed by applying the techniques to a dataset consisting of 33,238 active credit facilities from a financial institution operating in Kenya. Namely, the Accelerated Failure Time (AFT) ... -
Robust statistical learning for optimal classification of imbalanced data
(Strathmore University, 2021)Neurobiological disorders such as Learning Disabilities (LD) are increasing becoming a major concern in education and health sectors, hence, precise identification of these disorders is critical. While neuropsychological ... -
Spatial analysis of tuberculosis amongst teenagers in Kenya
(Strathmore University, 2018)Tuberculosis (TB) is the ninth leading cause of death worldwide and the leading cause from a single infectious agent, ranking above HIV/AIDS. Despite being preventable and curable, tuberculosis (TB) is the leading cause ... -
Spatial models for infants HIV/AIDS incidence using an integrated nested laplace approximation approach
(Strathmore University, 2019)Background: Kenya has made significant progress in the elimination of mother to child transmission of HIV through increasing access to HIV treatment and improving the health and wellbeing of women and children living with ... -
Using semi-Markov process to model incremental change in HIV staging with cost effect
(Strathmore University, 2021)Over the past years, parametric and non-parametric methods have been used in modelling cost and effectiveness according to one studied event or one health state. In this study we used semi-Markov model in which the ... -
The Zero Inflated Negative Binomial - Shanker distribution and its application to HIV exposed infant data
(Strathmore University, 2020)Motivated by HIV exposed infants (HEI) sero-conversion data, we provide an extension of Zero- inflated Negative Binomial (ZINB) distribution to Zero-Inflated Negative Binomial { Shanker (ZINB-SH) distribution. We review ...
