Comparative Analysis Of Sarima And Setar Models In Predicting Pneumonia Cases In The Northern Region Of Ghana

ABSTRACT  Acute respiratory infection (ARI) range, in spectrum, from mild colds and coughs to life threatening pneumonias. ARI particularly pneumonia is the major cause of morbidity and mortality among young children under five in developing countries with Ghana not an exception. In this study, we compared the linear SARIMA Model and the nonlinear two regime SETAR Model in predicting pneumonia cases in northern region of Ghana. Data on monthly pneumonia cases obtained from the Tamale Teachin...

The Application Of Queuing Theory To Customer Service At Selected Branches Of The Standard Chartered Bank Ghana Limited

ABSTRACT This thesis investigates the Application of Queuing theory to customer services at selected branches of the Standard Chartered Bank in Accra. The problem investigated was to determine among other things whether the customer service points of the bank functions well without bottlenecks or undue delays. That is this thesis intends to investigate, (a) If the bank current system of operation at the customer service points is satisfactory. (b) If not what changes are required to improve t...

Survival Analysis Of Male And Female Hiv/Aids Patients In Northern Region - A Kaplan & Meier Approach

ABSTRACT   Acquired Immune deficiency Syndrome (AIDS) is a disease caused by a virus known as Human Immunodeficiency virus (HIV). This virus attacks a person's immune system (white blood cells) and as such weakens the immune system and making the person vulnerable to opportunistic diseases e.g. tuberculosis, diarrhoea, to mention a few.  HIV was first diagnosed more than twenty years ago and up to now there is no known cure for the disease. The rate at which HIV is spreading in sub-Sahara ...

Misclassification Cost Sensitive Learning For Predicting Gonorrhea Infection Status In Ghana

ABSTRACT Gonorrhea, which is one of the most frequently reported sexually transmitted infection is caused by a bacterium called Neisseria gonorrhoeae. This disease can causes a serious public health problem worldwide, with about 88 million new infections occurring each year. Failure to treat this disease can result into pelvic inflammatory disease (PID), chronic pain and also damage the female reproductive organ. In males it can lead to reduced fertility and sterility. In developing countries...

Statistical Assessment Of Imputation Algorithms For Estimation Of Missing Values In Cross Sectional Data

ABSTRACT The validity and quality of data analysis relies largely on the data accuracy and completeness of the data matrix. Missing values are unavoidable statistical research problems in almost every research study and if not handled properly, may provide negative and bias conclusion. This study purposely sought to investigate the efficacy and accuracy of the convergence of five imputation algorithms: expectation maximization (EM), multiple imputation by chained equation (MICE), k nearest ne...

Modelling The Risk Factors Of Neonatal Mortality Using Survival Analysis

ABSTRACT Several strategies have been put in place in an attempt to reduce childhood mortality in Ghana, however the proportions of death among neonates are still quite high. The study therefore seeks to model neonatal mortality using survival analysis approach. The data used for the study was obtained from the neonate’s folders at St. Jude Hospital in Obuasi in the Ashanti Region between January 1, 2012 and December 31, 2015. Data on maternal characteristics was also obtained. Neonates who...

Factors That Influence Promotion Of University Of Ghana Lecturers: A Survival Analysis Approach,

ABSTRACT Survival analysis has been invaluable in studies involving time to an event. The methods encompassing the idea of Survival Analysis appears to be commended by most researchers particularly in the medicinal, engineering, agricultural and actuarial fields. This paper applied survival methods to promotion data of lecturers in the University of Ghana. The main objective was to identify the factors prominent in facilitating an early promotion of University of Ghana lecturers. The proporti...

Time Series Analysis Of Maternal Mortality In Ghana. A Case Study Of The Korle-Bu Teaching Hospital, Accra (2001 - 2013)

ABSTRACT This study examined the pattern of maternal mortality ratios as well as a spectral analysis of maternal mortality at the Korle - Bu Teaching Hospital in Accra from 2001 to 2013. It also fitted a stochastic model to forecast maternal mortality ratios for four quarters. Analyses were based on data available at the Bio-Statistics Department of the Obstetrics & Gynaecology directorate of the Korle - Bu Teaching Hospital in Accra for the period 2001 – 2013. The R-Consol statistical anal...

Statistical Analysis Of Water Level, Temperature And Humidity Using Cointegrated Vector Autoregression (Var) Models.

ABSTRACT The leading climate factors influencing availability of water are; temperature, relative humidity, precipitation, and evaporation. Water and agricultural production cycles are indisputably influenced by temperature and relative humidity. Temperature and relative humidity projections can therefore proficiently be employed in making decisions when optimal usage of water resources is of interest. Thus, the current study explored both the “long-run” and “short-run” impact of both...

Statistical Modelling Of Birth Spacing And Reproductive Health Of Married Women From Gomoa East District In The Central Region Of Ghana: A Survival Analysis Approach

ABSTRACT The objective of this research is to apply appropriate statistical techniques to model the length of time to successive births (birth spacing) within the reproductive health of mothers and identify the socio-demographic and sociocultural factors that cause variation in the length of birth interval. The data used in this study were collected using questionnaire from Gomoa East District 2014, where multi-stage cluster sampling was used as the sampling design. The clusters were defined ...

Modelling Ghana Stock Exchange Indices And Exchange Rates With Stable Distributions

ABSTRACT Most of the concepts in theoretical and empirical finance that have been developed over the last 50 years rest upon the assumption that the return or price distribution for financial data follows a normal distribution. But this assumption is not justified by empirical data. Rather, the empirical observations (financial returns) exhibit excess kurtosis, more colloquially known as fat tails or heavy tails. This research first described the stable distribution family - stable, Lev...

Analysis Of Spatial Differentials Of Income Inequality In Ghana: Application Of Bayesian Estimation

ABSTRACT The prime objective of the study was to introduce the application of a Bayesian method of estimation in the computation of the Gini coefficient. The bootstrap estimation technique was also employed to obtain confidence intervals for the estimated Gini coefficients which were used to statistically analyze the significant change of inter-household income inequality between 2005/06 and 2012/13 in Ghana with emphasis on the sex of head of household. Most of the methods used in calculatin...

Conditional Inference

ABSTRACT. Conditional inference is a branch of statistical inference in which observed data is reduced using either sufficient or ancillary statistics. This often simplifies inference about the parameters. In comparison to full likelihood methods, conditional inference theory's performance still needs validating in many areas. Some of these are the concern of this thesis.  

Forecasting Of Climate Variables In Mbeya Region

ABSTRACT Tanzania, like other countries in the world, is affected by climate change. There is enough evidence to substantiate this that comes from the increase of temperatures across the country over the past thirty years. Despite the mitigations approved to attack the problem of climate change in the country, forecasting of climate variables is a prerequisite. Studies about climate change that have been conducted in Tanzania have mainly focused on assessing the weakness and adaption to the ...
