Effect of exchange rate volatility on trade in Sub-Saharan Africa

Effect of exchange rate volatility on trade in Sub-Saharan Africa Abstract The volatile nature of exchange rates with the advent of floating regimes has received much attention in economic research. The volatility is generally perceived as negatively affecting international trade. While theoretical predictions and empirical outcomes appear mixed, the balance seems to tilt in favour […]

Mathematical Modeling of Predator-Prey models: Lotka-Volterra Systems

Mathematical Modeling of Predator-Prey models: Lotka-Volterra Systems The time dependent non-linear reaction-diffusion equation in predator–prey models in Lotka- Volterra system has been formulated and solved analytically and numerically. Analytical expressions for the prey and predator populations are derived by using the HPM. The primary result of this work is simple approximate calculations of prey and […]

A PANEL DATA APPROACH TO EXCHANGE VOLATILITY MODELS OF WEST AFRICA

CHAPTER ONE  INTRODUCTION/ Background of the Study “Does finance make a difference . . .?” Raymond Goldsmith (1969, p. 408). “Do economies with higher levels of financial development experience more or less volatility in economic growth rate?” Thorsten Beck, Mattias Lundberg and Giovanni Majnoni (2000) The impact of financial development on output volatility has been […]

MODELING AND FORECASTING OF ELECTRICITY CONSUMPTION USING ARMA AND EXPONENTIAL SMOOTHING

MODELING AND FORECASTING OF ELECTRICITY CONSUMPTION USING ARMA AND EXPONENTIAL SMOOTHING ABSTRACT The various available literature on modeling electricity consumption use time series models such as Autoregressive Moving Average (ARMA), Autoregressive Integrated Moving Average (ARIMA), Vector Auto-regression (VAR) and so on. In this research, Autoregressive Moving Average (ARMA)and Exponential Smoothing processes are used to fit […]

MODELLING MEAN SURFACE TEMPERATURE OF NIGERIA USING GEOSTATISTICAL APPROACH

MODELLING MEAN SURFACE TEMPERATURE OF NIGERIA USING GEOSTATISTICAL APPROACH ABSTRACT Understanding spatial variability of mean surface temperature (MST) of Nigeria is necessary for ecological restoration and national planning toward effects of unstable climate conditions. This study developed models for MST derived from two geosta- tistical procedures and Multiple Linear Regression (MLR) using measurements of monthly […]

Robust Detection Of Multiple Outliers In A Multivariate Data Set

ABSTRACT Many methods have been developed for detecting multiple outliers in a single multivariate sample, but very few for the case where there may be groups in the data set. We propose a method of simultaneously determining groups (as in cluster analysis) and detecting outliers, which are points that are distant from every group. Our […]
