DETERMINANTS OF TABLE EGG DEMAND IN MUBI NORTH LOCAL GOVERNMENT AREA, ADAMAWA STATE, NIGERIA

Abstract

The study modelled table egg data to uncover the factors influencing table egg demand in Mubi North Local Government Area of Adamawa State, Nigeria. The research entailed a household survey based on multistage sampling that elicited data from 260 households. Diagnostic checks such as Smirnov-Kolmogorov test was used to test for normality, link test for model specification, Cook-Weisberg test for heteroscedasticity, Durbin-Watson test for autocorrelation and variance inflating factor for multicollinearity. Result of diagnostic checks following ordinary least square (OLS) technique revealed heteroscedastic, auto-correlated and non-normally distributed data set for the study, hence, necessitated the robust regression to correct for those anomalies. The factors influencing demand of table egg were predicted with coefficients in tandem with a priori expectations. Price of egg and age of household heads showed negative coefficient, while, price of substitute (fish), income, education, household size, and knowledge on nutrition status of egg showed positive coefficient. The results further disclosed a high R² of 72.17 and low Root Mean Square Error (RMSE) of 8.2145 revealed that the model was correctly specified. The study validated theoretical postulation of inverse proportionality between price and demand of commodity; applicable also in model for table egg demand in the study.
