Health related quality of life is one of the growing subjects used for evaluating health conditions among patients who suffer from specific ailment.It has been assumed that identification of the variables is able to mirror the one's general health conditions.However,formulating the extent of contribution is multiple variable towards overall health conditions is not straight forward as the arbitrary nature of HRQL variables.This paper aims to model the relationship between HRQL variables using...
Motherless babies have nowadays become common because of moral deca-dence of the society, young people who cannot cater for themselves and ndthemselves put in a family way end up abandoning their babies. The increas-ing hardship of the present economic recession has increased the incidence ofburden on families and the consequent loss of rm control of family members.Time series analysis is use to model the admission and release of children inthe motherless or orphanage home and the data use fo...
This paper addressed the popular issue of collinearity among explanatory variables in the context of a multiple linear regression analysis, and the parameter estimations of both the classical and the Bayesian approaches were compared using Mean Square Error (MSE) and Absolute bias. Five sample sizes: 10, 25, 50, 100 and 500 each replicated 1000 times were simulated using Monte Carlo method. Four degrees of correlation representing no correlation, weak correlation, moderate correlation and ...
It has been observed over the years that real life data are usually non-conforming to the classical linear regression assumptions. One of the stringent assumptions that is unlikely to hold in many applied settings is that of homoscedasticity. When homogenous variance in a normal regression model is not appropriate, invalid standard inference procedure may result from the improper estimation of standard error when the disturbance process in a regression model present heteroscedasticity. When...
School, colleges and universities have no worth without student. Students are most essential asset for any educational institute. The social and economic development of the country is directly linked with student academic performance. The determinants of students' performance have been the subject of ongoing debate among educators, academics, and policy makers. There have been many studies that sought to examine this issue and the findings of these studies point out to hard work and disciplin...
ABSTRACT Road accident has been of great social and economic concern. It has became a total topic for scientific investigation. The number of deaths on the road today, particularly on the major roads of rural-urban areas are what motivated me in writing this project. This study is essentially based on the Statistical Analysis of Road Accidents recorded in Enugu rural-urban roads from 1993 to 2000 with the objectives to; identify the causes of road accidents in Enugu and compare the attend...
Abstract Based on presentation of the principles of nonorthogonal problem, we discuss the difference of some approaches. A simple procedure to include the R-squared and Root Mean Square Error (R.M.S.E) is proposed and tested. The results showed that the Partial Least Square Regression provides better predictions due to a small R.M.S.E value. Keyword. Nonorthogonal, Mean Square, Partial Least Square, R Square. Table of Content 1.0 Introduction 2.0 The Ordinary Least Square Model 2.3 Ridge Re...
AbSTRACT This research work is based on the construction of control chart for quality characteristics of Coke liquid (Sodium content, Sugar content and Volume) which may be used for control of future products of the Coca-Cola Company. Secondary data collected from Coca- Cola Company, Idokpa, Benin City Plant was analysed using Control Chart for process variability and process average. Through the application of statistical Quality Control technique, the product quality was examined and proces...
ABSTRACT In this project, Partial Least Square Regression was compared with Ordinary Least Square Regression (OLSR) to handle the problem of multicollinarity and small sample size on all Nigeria Insurance Company’s expenditure data. The prediction methods have been compared for efficiency through Root Mean Square Error (RMSE) and Mean Square Error (MSE). It is found that in this project Partial Least Square Regression (PLSR) provides better prediction as compared to the Ordinary Least Squa...
Outliers are every day problems encountered in all spheres of life. This work addresses the different methods of labelling outliers and as well highlights the applications of outliers in real life processes
ABSTRACT Rising cost of foodstuffs affect the welfare of majority of Nigerians who live below the poverty line of one dollar per day. The study examined the relative changes in prices of staple foods in Imo State. The study collected secondary data from National Bureau of Statistics (NBS) on the yearly prices and quantities of staple foods in Imo State over a period of seven (7) years (2006-2012) .The Fisher’s Ideal Index was used to analyze the data. The study revealed that prices of stapl...

INTRODUCTION Hajia Gambo Sawaba General Hospital since its inception in 1975 has received considerable amount of people, for treatment medical advice, family planning and a host of other reason. Different categories of people have patronized the hospital for its efficiency. It is therefore in the best interest of the researcher to use his or her knowledge of statistic application is the attendance of ill health (patients) attending the hospital. It does not and here the research as will lo...
ABSTRACT This research work was aimed at carrying out statistical analysis of federal government’s revenue and expenditure 2003-2008. Secondary data was obtained from National Bureau of Statistics. The statistical package used is Mintab. The result of the analysis shows that there is positive and strong relationship between expenditure and revenue 0.938 and the regression equation is expenditure = 123 + 0.367 revenue. The regression equation shows that when the revenue increase, the expendi...
ABSTRACT Statistics is playing an important role in virtually all aspect of human life. This role is used to analyze a project, which is aimed at analyzing the rate of crime in Kuje-Abuja. This analysis is meant for correction, up-dating, forecasting the future accordance events. The objectives of the project are the criminal offences in Kuje. The project comprises of five chapters; chapter one, contains the introduction of the project and the historical background of Kuje Police Station also...
