Multivariate Jackknife Delete-5 Algorithm On The Effect Of Nigeria Foreign Trade On Foreign Exchange Rates Of Naira (1960-2010).

摘要

Abstract: In this paper we presented the multivariate extension of multiple linear regression using Jackknife techniques in modeling the relationship between m set of responses and a single set of r regressors . The responses are Oil Import Non-Oil Import Oil Export Non-Oil Export which is classified as Nigeria Foreign Trade, while the regressors are Exchange Rate of US Dollar and Exchange Rate of Pounds sterling's which are classified as Foreign Exchange Rate. We proposed new algorithm for estimating the parameters of multivariate linear regression using the jackknife technique. The results obtained using Jackknife delete-5 algorithm competes favorably with the existing methods. Consequently Time Series approach was adopted for future prediction of the Nigeria Foreign Trade from year 2011 to 2020. Evidently, the time series plot depicts an increase of exchange rate of US Dollar and Pounds Sterling over the years under consideration. Thus, this will definitely affect Nigeria Foreign Trade negatively which could be harmful to the Nigeria's economy.
