Item Female Circumcision in Nigeria, Prevalence and Attitudes(Library and Publication Committee, University of Ilorin, 2012) Abiodun, A.A.; Oyejola, B.A.; Job, O.Nigeria is one of the countries in Africa where female circumcision is widely practiced. Information about the prevalence and attitudes towards its practice and predictors associated with its support were collected from the 2005 National HIV/AIDS and Reproductive Health Survey (NARHS) on females aged 15-49 and males aged 15-64 years. The prevalence of female circumcision is more in the southern part of Nigeria than the Northern part, with South West and South East recording the highest percentages. There is a marked decrease of the practice in the younger age cohorts compared to the older age cohorts. As the level of education increases, the likelihood of supporting the practice of female circumcision reduces and regular use of media of communication such as radio and television is an influential factor against the practice of female circumcision in Nigeria.Item Performances of Ordinary and Generalized Least Squares Estimators on Multiple Linear Regression Models with Heteroscedasticity(Akama University, 2016-05) Adejumo, A.O.; Job, O.; Isaac, T.D.; Oyejola, B.A.This paper focuses on the impact of heteroscedasticity on the estimate and variance of model parameters by studying the performances of Ordinary Least Square (OLS) and General Least Square (GLS) estimators in multiple linear regression models with two independent variables only and error term characterized with different magnitudes of heteroscedasticity related to predictors at different sample sizes. This research explored the patterns of the variance estimates offered by the two estimators when data is front with heteroscedasticity. Also the studies explored the situations where concepts of substitute, complementary or joint demands/supply may reflect in the stochastic characterization of the error term. From Monte Carlo simulation studies using R-package the GLS estimator maintains its superiority over the OLS in multiple linear regression models.
