Abstract

As the world continues to be unpredictable, the need for diversification of a nation's exports, especially for developing countries like Nigeria, cannot be overstated. This study was designed to examine the nexus between agriculture exports and economic growth in Nigeria using secondary data from 1991 to 2020. Using the Augmented Dickey fuller test, co-integration analysis, error correction, and Granger causality analysis, the results revealed that the covariates were stationary (I) and that there is a significant long-run co-integrating relationship between agricultural exports and economic growth (p values <0.05). The results further revealed that about 86% of the variation in agriculture exports was explained by the predictor variables (economic growth). The model diagnostic check revealed that the estimates were not spurious as the errors were linear, not serially correlated, and homoscedastic (all p-values > 0.05). However, there was not enough evidence of a causal relationship between economic growth and agricultural exports, though it was found that there was causality between population growth and the unemployment rate. The study recommends, among others, that employment and security be provided for Nigerians.

Abstract

This study investigates the modeling of some macroeconomic variables in Nigerian using multivariate monthly time series data from January 2010 to December 2019. The study examined two inflation factors which include money supply (MS) and exchange rate (ER) which are of great importance in determining inflationary effect in any economy. If MS is greater than ER then it can be said that the economy is experiencing rise in inflation and vice versa. Based on the analysis of implementing a vector autoregressive model to the data at stationarity using the Augmented Dickey–Fuller (ADF) test, Inflation rate (IR) was found to be significant only at lag 2 of IR. However, MS was found to be significant at lag 1 of ER and ER was significant at lag 1 and lag 2 of ER. The impulse response function plots clearly showed an unstable IR on MS and ER but at the later end of the periods, Nigeria IR tends towards a positive stability on MS and ER, respectively.

Abstract

In this research, the application of Exponentiated Burr-V (EBV) distribution is presented and compared with other competing distributions which include Exponentiated Pareto distribution, Exponentiated Lomax distribution, Exponentiated Gumbel distribution, and Exponentiated Generalized Inverse Exponential distribution. The maximum likelihood estimation method was used in estimating the EBV and the four competing distributions. The loglikelihood (LL) and Akaike Information Criteria (AIC) was applied for determining the best fitted distribution and the distribution with the largest LL and smallest AIC is considered the best fitted distribution. The data used is on bladder cancer which is a widely used data from Lee and Wang (2003), Lemonte and Cordeiro (2011), Luz, (2012), and Kazeem et al., (2014). The results obtained showed that the EBV distribution has the largest LL value of 2950.726 and the smallest AIC value of –5895.452. The LL and AIC values imply that the EBV distribution is a very competitive distribution in fitting the bladder cancer data and it is an appropriate distribution for fitting asymmetric or negatively skewed and high kurtosis datasets.
