Modeling and Forecasting of Ghana’s Inflation Volatility
In this paper, we assessed volatility of Ghana’s inflation rates for 2000 to 2018 using the auto-regressive conditionally heteroskedasticity (ARCH), generalized ARCH (GARCH), and the exponential GARCH (EGARCH) models. The inflation data were obtained…
Modeling Cholera Epidemiology Using Stochastic Differential Equations
In this study, we extend Codeço’s classical SI‐B epidemic and endemic model from a deterministic framework into a stochastic framework. Then, we formulated it as a stochastic differential equation for the number of infectious individuals I(t) under…
Modeling downtime severity of telecommunication networks using discrete time Markov chains
Telecommunication network reliability remains a top priority for both customers and service providers. Downtime can result in revenue loss for providers and productivity loss for customers. Thus, accurately predicting downtime severity can help…
Modeling the Causes of Power‐Related Network Outages Using Discrete‐Time Markov Chains
In this paper, we model the causes of power‐related network outages in Ghana using discrete‐time Markov chains. We used data consisting of 2,756 small‐scale carrier telecommunications outages occurring in Ghana, with accompanying root causes over a…
Modeling the Trend of Performance of the Manchester United Football Club in the 1960-2013 English Premiership
This research studied the trend of performance of Manchester United Football Club in the 1960-2013 English premiership seasons. The three main variables involved in this study are the number of games won, games drawn and games lost by Manchester…
Modeling total quality management framework for higher education institutions in Ghana
The aim of this study is to model an appropriate Total Quality Management (TQM) framework for Higher Education Institutions (HEIs) in developed and developing countries particularly Ghana. The driving force for this study is the low-quality standards…
