On Optimal Complete Replicated Rotatable, Orthogonal, Efficient and Relative Efficient Central Composite Designs

ABSTRACT Replication is the repetition of the treatments under investigation to different experimental unit. Replication is essential for obtaining a valid estimate of the experimental error and to a greater extent, increasing the precision of estimating the pairwise difference among the treatment effects. It is on this note that when full replication (replication of cube and star point) is made, there exists need for optimal replication for the purpose of minimizing biasedness. Some variatio...

Agricultural Production and Economic Growth in Somalia from 1986 to 2016

ABSTRACT The study aimed at examining the effect of agricultural production on economic growth in Somalia from the period of 1986 to 2016 using time series data. Specifically, the study examined the causality and the effect of agricultural production on GDP growth. The objective was motivated by the fact that the problem statement emphasized that agricultural production has not yielded expected economic growth in Somalia. The study hypothesized that no casualty between agricultural production...

Specifically, the study aimed at examining how each of these variables affects population growth. The objectives were; to examine the relationship between mortality rate and population growth rate in Uganda, to determine the relationship between fertility rate and population growth rate in Uganda are and to a...

Multivariate Analysis to Assess the Effectiveness of the National Health Insurance Scheme (Nhis) In Ghana

ABSTRACT  This thesis provides an assessment of the effectiveness of the National Health Insurance Scheme (NHIS) in Ghana implemented by Act 650 and L.I 1809, 2004. This assessment is done by taking the Akuapem South Mutual Health Insurance Scheme, selected health facilities in the NsawamAdoagyiri Municipality and Akuapem South District that provides health insurance services and health insurance users as case study. The selected health facilities are the Nsawam Government Hospital, Pokrom H...

Maximum Likelihood Estimation Of Parameters For Poisson-Exponential Distribution Under Progressive Type I Interval Censoring

Abstract The problem of estimating the parameters of Poisson-Exponential distribution under progressive type-I interval censoring is considered. Previously, researchers have considered maximum likelihood estimation under the progressive type-I interval censoring scheme for various distribution, but no research has considered Poisson-Exponential. Poisson-Exponential is a two-parameter lifetime distribution having an increasing hazard function. It has been applied in complementary risks problem...

Maximum Likelihood Estimation of Parameters of Lomax Distribution Based on Progressive Type-II Hybrid Censoring Scheme.

    Abstract Lomax distribution is an important lifetime distribution. The process of obtaining estimates of parameters for di_erent lifetime distributions under various schemes still remains an area of interest. In Lomax distribution, parameter estimates have been obtained using ordinary procedures like Newton Raphson when the test units follows a progressive Type-II hybrid censoring scheme whereby within most cases the obtained values do not converge easily to the true value. The MLEs a...
