Estimating Average Value of Nigeria GDP Using Dummy Variables Regression Model

Abstract

Dummy variables assign the numbers ‘0’ and ‘1’ to indicate membership in any mutually exclusive andexhaustive category. The number of dummy variables necessary to represent a single attribute variable is equal to the number of categories in that variable minus one. In this study, dummy variables regression analysis was applied to estimate the average GDP at various quarters; the GDP data was described and graphically presented. A regression model was estimated to determine the average value for each quarter, the seasonal component, and average GDP confidence interval. The study provides the seasonal prediction and revealed that the average GDP in the second, third and fourth quarters are not statistically difference except the first quarter. The result of the studies showed that Nigeria realised the highest income generated by productions and services in the country in the fourth quarter of every year.

Keywords: Average GDP, Dummy Variables, Seasonal Component and Time Series
