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...
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 ...
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.
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 ...
ABSTRACT This study focused on O level performance of students in Dodoma. The study employed mixture research design whereby a total of 294 respondents from seven schools in Dodoma municipal were involved. Data were collected through printed questionnaires and documentary reviews. Tables, bar charts, line chart and logit model were used to analyze data collected through Microsoft office excel 2013 version and SPSS IBM 21. The main findings of this study indicated that among many other factor...
ABSTRACT Bayesian modelling as well as decision tree methods are some of the efficacious classification methods in credit scoring applications. Application of these methods to credit scoring provides several advantages, which are highlighted in the literature. In this research, a Bayesian hierarchical model using the latent variable approach coupled with the classification and regression tree ‘CART’ approach is applied to classify customers who applied for loans into potential defaulters ...
ABSTRACT It was asserted that University and university systems around the world are faced with rapid growing demand and decreasing or static government investment (Marcucci and Johnstone, 2010). In response to this assertion, many countries introduced cost-sharing in order to preserve the quality of higher education. In order not to deny academically talented young people from poor families from accessing higher education, governments and individual institutions started offering financial as...
ABSTRACT The right to a fair hearing within a reasonable time by a court when charged with a criminal offence and to a speedy and public trial in all criminal prosecutions are some of the basic rights guaranteed by the 1992 constitution of the Republic of Ghana. In this study, survival analysis was used to determine the average time to justice delivery for the upper east and west regions of Ghana both first collectively and as individual entities. Type of cases that last longer in courts and...
ABSTRACT The water level at a particular time determines the amount of hydro-electrical energy generated by the Akosombo dam. The Akosombo dam serves as the main source of electrical energy in Ghana. This research work sought to estimate and assess the impact of the Bagre Dam as an intervention event on the Akosombo Dam. Daily water level data covering the period 1982 to 2002 which was obtained from the Volta River Authority (V.R.A), Ghana was used in carrying out this study. Empirical resul...
ABSTRACT Birth weight is one of the key indicators of the health and viability of the newborn infant and a person’s personality. It is desired that birth weight should be in the range of 2.5kg and 4.0kg. Low Birth Weight (LBW) has been defined by the World Health Organisation (WHO) as weight at birth less than 2.5kg. This study considered causal variables of LBW among infants in the Sunyani Municipality and sought to postulate a statistical model for predicting the likelihood of giving bir...
ABSTRACT Regular assessment of weight gain among babies has been a way of assessing their health status and growth. This study assessed the weight gain among babies under different forms of feeding practices for the first nine months after birth. The feeding practices focused on in this study are Exclusive Breastfeeding (EBF), Breastfeeding with water only (BFW), Breastfeeding with any other food including water (BFWO) and Non-Breastfeeding (NBF). Data was obtained from Mampong Babies Home, ...
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...
Abstract The main purpose of the study was to examine the performance of students in mathematics based on their understanding, knowledge and perception, in Senior High Schools. The study considered all second year students in Nalerigu Senior High School in the East Mamprusi District of the northern region. Well structured questions were administered to 30 males and 30 females through stratified random sampling. Preliminary analysis reported high mean performance for males as compared to fema...
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...
ABSTRACT Since the introduction of the Markowitz mean-variance optimization model, several extensions have been made to improve optimality. This study examines the application of two models - the ARMA-GARCH model and the ARMA- DCC GARCH model - for the Mean-VaR optimization of funds managed by HFC Investment Limited. Weekly prices of the above mentioned funds from 2009 to 2012 were examined. The funds analysed were the Equity Trust Fund, the Future Plan Fund and the Unit Trust Fund. The retur...
