On the Multivariate Analysis of the level of Use of Modern Methods of Family Planning between Northern and Southern Nigeria

The recently published 2013 National Demographic and Health Survey (NDHS) results show a great apathy in the use of modern family planning methods, despite the whooping financial and material resources being plunged into it. Worried by this insignificant level of use, the need to discern where more of the apathy is (North or South) becomes inevitable. This paper, therefore, stratified the NDHS data on the level of use of the modern methods of Family Planning into two, adopted the Hotellin

The Relationship between Spousal Age Difference and Violence against Wife in Nigeria: A Generalized Linear Modelling Approach

The act of violence against wife is condemnable and attracts various legal penalties, globally. This article attempts to find a link between spousal age difference and violence (Emotional, Physical and Sexual) against wives in Nigeria. The result show that wives who are older than their partners are more likely to experience sexual and emotional violence; also, wives who are same age as their husbands are more likely to experience sexual violence; whereas wives who are 1-4 years younger than their husbands are more likely to experience physical violence; while wives 5 years or more younger than their husbands are generally less likely to experience any form of violence

Marshall-Olkin generalized Erlang-truncated exponential distribution: Properties and applications

This article introduces the Marshall–Olkin generalized Erlang-truncated exponential (MOGETE) distribution as a generalization of the Erlang-truncated exponential (ETE) distribution. The hazard rate of the new distribution could be increasing, decreasing or constant. Explicit-closed form mathematical expressions of some of the statistical and reliability properties of the new distribution were given and the method of maximum likelihood estimation was used to estimate the model parameters. The usefulness and flexibility of the new distribution was illustrated with two real and uncensored lifetime data-sets. The MOGETE distribution with a smaller goodness of fit statistics always emerged as a better candidate for the data-sets than the ETE, Exp Fréchet and Exp Burr XII distributions

The Kumaraswamy G Exponentiated Gumbel type-2 distribution

The distribution due to Okorie et al. (2016) is further extended to a wider family of distribution called the Kumaraswamy Generalized Exponentiated Gumbel type-2 distribution. Twenty two distributions are identified as sub-models of the new distribution. Some of its important statistical properties are explicitly derived and the parameters of the new distribution are estimated through the method of maximum likelihood estimation.Keywords: Gumbel type-2; Kumaraswamy; Weibull; Fréchet; Inverse exponential and Rayleigh distributio
