Bayesian Hierarchical Model With Classification And Regression Tree In Predicting Loan Default

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 ...

Some Approaches To Modelling Need-Based Finanacial Aid To Needy Students In The University Of Ghana

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...

Survival Analysis Of Average Time To Justice Delivery In Upper East And Upper West Regions Of Ghana.

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...

Modeling The Effect of The Badgre Dam on The Water Levels of The Akosombo Dam: Time Series Intervention Analysis

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...

Proximate Determinants Of Low Birth Weight Incidence In Sunyani Municipality, Ghana

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...

Statistical Analysis Of Weights Of Babies Under Different Forms Of Feeding Practices A Case Study Of Mampong Municipality

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, ...

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...

Statistical Analysis Of Sex Difference In Understanding, Knowledge And Perception Of Mathematics In Nalerigu Senior High School.

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...

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...

Investment Portfolio Optimization With Garch Models

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...

Determinants Of The Promotion Of University Of Ghana Lecturers: A Survival Analysis Approach

ABSTRACT The desire to reach the peak of one’s chosen career makes us curious and hardworking enough to attain positions and ranks. This is no different in the academia where lecturers look forward for promotion. However, there are perceived and actual factors contributing to promotion among University of Ghana lecturers which is examined. The factors contributing to promotion of University of Ghana lecturer and how long it takes a lecturer to earn a first promotion, were the objectives of ...

A Comparative Analysis of Forecast Performance Between Sarima And Setar Models Using Macroeconomic Variables in Ghana

ABSTRACT Most macroeconomic variables such as; inflation, GDP and others have been described by most financial and economic time series analysts to exhibit nonlinear behaviour. Therefore, to cater for this behaviour, the nonlinear class of models have been largely adopted to model and forecast such time series. In this study, the Keenan and Tsay tests for linearity showed inflation and CIC rates follow threshold nonlinear processes. Hence, the two-regime SETAR model was adopted to accommodat...

A Statistical Assessment Of The Role Of Gender In Modulating Episodic Prospection

ABSTRACT The study sought to assess whether gender contributes towards how prospection modulates delay discounting. The relevant data for the study was generated by means of three sets of behavioral experiments; where by equal number of males and females under took inter-temporal tasks involving choosing between instant though smaller reward and deferred yet larger reward, while imaging positive, negative, and neural episodes respectively. In order to test the various hypotheses related to th...

Statistical Analysis of The Impact of The GCNET on Revenue Performance in Ghana: (A Case Study of TEMA Port)

ABSTRACT In most economies of the world, import revenue makes up a significant part of total government revenue (Zhu & Kotz, 2010). Since economic development in a nation is largely driven by the amount of revenue mobilized, import revenue makes an impact on how well an economy develops. This study aims at assessing the contribution of Ghana’s import revenue mobilization to Gross Domestic Product (GDP) growth and investigate the impact of the implementation of the Ghana Community Network (...
