Robust Linear Classifier For Unequal Cost Ratios Of Misclassification, Oludare S. Ariyo, A O. Adebanji
Robust Linear Classifier For Unequal Cost Ratios Of Misclassification, Oludare S. Ariyo, A O. Adebanji
CBN Journal of Applied Statistics (JAS)
This paper focuses on the robust classification procedures when the assumption of equal cost of misclassification is violated. A normal distribution based data set is generated using the Statistical Analysis System (SAS) version 9.1. Using Barlett’s approximation to chi-square, the data set was found to be homogenous and was subjected to three linear classifiers namely: Maximum Likelihood Discriminant Function (MLDF), Fisher’s linear Discriminant Function and Distance Based Discriminant Function. To Judge the performances of these procedures, the Apparent Error Rates for each procedure is obtained for different cost ratios 1:1, 1:2, 1:3, 1:4 and 1:5 and sample sizes 5:5, 10:10, …
A Kalman Filter Approach To Fisher Effect: Evidence From Nigeria, Omorogbe J. Asemota, Dahiru A. Bala
A Kalman Filter Approach To Fisher Effect: Evidence From Nigeria, Omorogbe J. Asemota, Dahiru A. Bala
CBN Journal of Applied Statistics (JAS)
This paper investigates evidence of a Fisher effect in Nigeria by employing quarterly CPI inflation and Nominal interest rates data. For a more robust result we conducted integration and cointegration tests in order to examine time-series properties of the variables. Using Co-integration and Kalman filter methodologies, the study did not find evidence of a full Fisher effect from 1961:1-2009:4. This result indicates that nominal interest rates do not respond one-for-one to changes in inflation rates in the long run despite the presence of positive relationship among the variables. Our study recommends the adoption of potent policies aimed at checking inflation …
Building Dynamic Stochastic General Equilibrium Models For Monetary Policy Analysis, Charles N. O. Mordi, Michael A. Adebiyi
Building Dynamic Stochastic General Equilibrium Models For Monetary Policy Analysis, Charles N. O. Mordi, Michael A. Adebiyi
Economic and Financial Review
Dynamic Stochastic General Equilibrium (DSGE) models are powerful tools that provide a coherent framework for policy discussion and analysis. In principle, they can help to identify sources of fluctuations, answer questions about structural changes, help to forecast and predict the effect of policy changes, and perform counterfactual experiments. Against this background, this paper aims at providing an insightful discussion on DSGE models by developing a simplified version of the models to explain the behavior of key macroeconomic variables in Nigeria namely: the growth rate of gross domestic product (GDP), headline inflation, exchange rate and the monetary policy rate. The estimated …

A Common Economic Space For The West African Monetary Zone (Wamz): Imperatives For Financial Systems Development, A. O. Adenuga, K. K. Ogunjuiba, M. E. Obiechina
A Common Economic Space For The West African Monetary Zone (Wamz): Imperatives For Financial Systems Development, A. O. Adenuga, K. K. Ogunjuiba, M. E. Obiechina
Bullion
The international financial turmoil of the 21 century has provoked much reflection and analysis within the international community on ways to strengthen the international financial architecture. It left behind important lessons, while exposing the limitations of individual country policy frameworks for preventing a systemic crisis. However, the issue of whether a common economic space is feasible within the West African Monetary Zone is still doubtful, given current efforts towards monetary union in Sub-Saharan Africa. This paper adopts an empirical review approach, identifying benefits and key constraints to a common economic space in the WAMZ vis-à-vis macroeconomic development in the WAMZ, …
