ABSTRACT Studies into income, expenditure and standard of living of individuals and households are well documented in literature. Many of these studies cover different forms of poverty indicators and variables. The methods used in this analysis were mainly econometric models. The study is concerned with determining the indicators and variables that possibly influence income, expenditure and living standard of households. The objective here is to model the determinants of living standards or p...
ABSTRACT Most of the methodologies employed in analyzing stock time series data are based on the assumption of Efficient Market Hypothesis which does not assume long range memory or dependence in the data generating process. However empirical evidence from stock data fails to support the lack of dependence especially in developing countries. This study investigated the long range memory in some selected equities on the Ghanaian stock market using non-parametric and parametric methods. Using t...
ABSTRACT One of the major problems of multiple linear regression analysis is multicollinearity of the independent variables. The existence of multicollineariity on climate variables such as relative humidity, solar radiation, rainfall, sunshine and temperature on the response of agricultural output may lead to inflation of standard error of the regression coefficients or false non-significant p-value. In this study, monthly data spanning from 1980-2012 obtained from the Nigeria Institute...
ABSTRACT This study evaluated the relationship between possible medical and social factors affecting maternal deaths. A conceptual framework was developed to help identify, classify, model and resolve these factors (by implementing the recommendations). A generalized linear model was fixed using the ‘R’ statistical analysis software. Three data sets (2016 and 2013 data sets on maternal mortality, and a data set on the causes of maternal deaths) were used in the analysis, which showed wide...
ABSTRACT Education has been defined as the act or process of imparting or acquiring general knowledge, developing the process of reasoning and judgment, and generally of preparing oneself or others intellectually for mature life. It is an unarguable fact across the globe that a nation’s development rests on the education of its citizens. But for a country to achieve a high literacy rate, basic education, which is regarded as the foundation should be held in high esteem. For this reason, gov...
ABSTRACT This study demonstrated the application of Markov S-I-R model and other statistical methods in exploring HIV, Tuberculosis (TB) and Hepatitis B (HB)disease outcomes using Ghanaian data. Secondary datasets from cohort studies were collected from records from the Ashanti Regional Hospital. Relevant disease metrics as well as transition probabilities were generalized for each disease. Method of Competing risks was used to further estimate the crude, partial crude and net probabilities o...
ABSTRACT Multidimensional scaling is a technique used to picture, visualize or locate objects in a map or Shepard diagram, Buja et ai, (2004). In this dissertation, the multidimensional scaling method has been applied to visualize approximate Iodations of eleven sampled local governments in Kebbi State. The symmetric distance matrix 'D' has been processed from an atlas of Nigeria by Eunice, (1979). The data has been transformed into inner-product matrix B by double centering, using Mardi...
ABSTRACT This research aimed at fitting the canonical correlation model that is capable of determining whether literacy level, age, marital status and gender are risk factors for HIV/AIDs. The data used is obtained from Heart to Heart centre situated in General Hospital Minna, Niger State in June 2013. The Statistical package used to analyze the data is NCSS (Number Cruncher Statistical System) 2007 package and the result shows that the first set of variables measured the correlation of ...
ABSTRACT The problem of spurious correlation analysis, e.g. Pearson moment-product correlation test is that the data need to be normally distributed. This research work compares spurious correlation methods using some non-normal probability distributions in order to obtain the method with the best degree of association among them. The methods were compared using proportions of rejecting true null hypothesis obtained from t and z test statistics for testing correlation coefficients. Data ...
ABSTRACT Rating undergraduate programs of higher educational institutions is a common, albeit argumentative practice. However, prospective students, parents and faculty members deserve the opportunity to compare the relative strengths of the programs and the institutions when making educational and (or) personal decisions. The main objective of this research is to evaluate statistics programs indicators of the tertiary institutions. The researcher actually wants to know which of the indicator...
ABSTRACT The estimation of multiple characteristics using Probability Proportional to Size (PPS) sampling scheme has introduced some complexities in sample surveys. It requires transformation of auxiliary information into probability measures and the utilization of correlation coefficient between study variables y and measure of size x. Existing estimators of finite population characteristics are rigidly specified by a fixed order of positive correlation between y and x and are assumed effic...
ABSTRACT The study looks at identification of outstanding and abysmal performances of students in examinations involving seven common subjects taken in the first year at Ghana Senior High School in Koforidua. The scores of the students, who were grouped into six different program classes, in the seven subjects constituted the data for the study. In order to achieve the objective of the study using this high dimensional data set, a multivariate data analysis technique (the Principal Componen...
ABSTRACT The Bayesian approach conveys information not available in the data but on prior knowledge of the subject matter, which enables one to make probability statements about the parameters of interest, while the classical approaches deals solely with the data. Several researches on the classical approaches have shown them to be sensitive to multicollinearity, a violation of one of the assumptions of multi-equation models which often plagues economic variables. Studies on the performance ...
ABSTRACT This study is about diseases reported at the outpatient departments (OPD) in the Greater Accra Region. The objectives of this study was to find the trend of the various diseases reported at the Outpatient Departments, forecast 2007 reported diseases and finally, to identify the most reported disease(s) within the period. Data was obtained from the Adabraka Polyclinic which is the coordinating center for the region's health statistics. The data covered the period 1996 to 2006. Trend ...
ABSTRACT The study was to determine beneficiary community members’ expectation of the benefits of social development projects in Education Rights, Gender and Women’s Rights and Food Rights. Sixteen criteria were gotten, initially, using participatory rural appraisal. These were included in the basic information section of a questionnaire. The questionnaire also sought classification and identification information of respondents. It was administered to one hundred respondents selected thr...
