Identification of Outstanding Performances in Senior High School Examinations: A Principal Component Approach

ABSTRACT The study looks at identification of outstanding and abysmal performances of students in examinations involving seven common subjects taken in the first year at Ghana Senior High School in Koforidua. The scores of the students, who were grouped into six different program classes, in the seven subjects constituted the data for the study. In order to achieve the objective of the study using this high dimensional data set, a multivariate data analysis technique (the Principal Componen...

THE Bayesian Approach to Estimation of Multi-Equation Econometric Models in the Presence of Multicollinearity

ABSTRACT The Bayesian approach conveys information not available in the data but on prior knowledge of the subject matter, which enables one to make probability statements about the parameters of interest, while the classical approaches deals solely with the data. Several researches on the classical approaches have shown them to be sensitive to multicollinearity, a violation of one of the assumptions of multi-equation models which often plagues economic variables. Studies on the performance ...

STATISTICAL MODELING OF THE GHANAIAN WEATHER USING MARKOV CHAINS: A Case Study of Accra, Kumasi and Tamale, 2003-2007

ABSTRACT In this dissertation, Markov chain was used to model the rainfall pattern and sunshine duration for three regional capitals in Ghana (Tamale, Kumasi and Accra). Data on mean monthly averages and daily figures of measured parameters (sunshine duration and rainfall) for five years were used. To achieve these goals, a statistical basis was presented before adopting the three main approaches for modeling. Transition Matrix shows the short-run behavior of Markov chain; the steady-state pr...

VOLATILITY MODELLING OF PRICES OF COCOA BEANS TRADED ON THE INTERCONTINENTEAL EXCHANGE (ICE)

ABSTRACT  This study compares the performances of ARIMA, ARCH, GARCH, EGARCH and GJR-GARCH on their abilities in modelling and forecasting the volatility of world cocoa bean prices on the London Intercontinental Futures Exchange using weekly averages of prices in Great Britain Pounds from January 1985 through December 2017.

EXTREME VALUE ANALYSIS OF TEMPERATURE AND RAINFALL: CASE STUDY OF SOME SELECTED REGIONS IN GHANA

ABSTRACT  Rainfall and temperature are important climatic factors for crop production and affects humans’ basic needs such as health, shelter, food and water in Ghana. However extreme rainfall causes flooding which can lead to loss of lives, properties among others. Extreme temperature also causes drought, hot and cold spells among others which have adverse implications on human beings and agriculture. It is therefore important to know about occurrences of such extreme events and thei...

To this end, the study focuses on various factors. The objective of the study therefore is to determine the latent factors  that  are  considered  by  the...

MODELING POVERTY STATUS OF GHANAIANS: A LOGISTIC REGRESSION APPROACH

ABSTRACT The poor are not evenly distributed within the country and they do not share the same socio-economic and demographic characteristics. It is against this  background that analysis of the characteristics  that differentiate the poor from  the  non-poor  in  Ghana  cannot  be  underestimated.  Poverty  indicators make it possible to analyze the likely  determinants and are, therefore, essential for formulating  policy  interventions that may contribute  directly or ...

Factor Analysis and Survey Design

This paper analyzes factor analysis, discussing both confirmatory factor analysis (CFA) and exploratory factor analysis (EFA), as they relate to survey design. Shi et al. (2017) is discussed and compared to another study applying factor analysis by Tungkunanan (2020). A discussion of how factor analysis is used in my current field and potentially for COVID research is also explored. First, however, a discussion of the history of factor analysis, how it was designed, improved, and is currently...
