ABSTRACT The purpose of this study was to find out the appropriate probability distributions that fit suitable to the motor insurance claims in respect of motorcycles, cars, and heavy vehicle insurance claimed amounts. The specific objectives were: to estimate the probability distributions considered, to identify appropriate model that fit best to the motor insurance claims amounts among eight distributions and to test the goodness of fit of the fitted probability distribution models. Daily ...
Abstract Stated preference (SP) experiments are becoming an increasing popular survey methodology for investigating air travellers’ choices. Analysis of this behaviour, which is an element of the demand prediction, helps for a better future planning and development of competing airlines. In this thesis, emphasis is stressed on the stated preferences of passengers in choosing between low-cost carriers (LCC) and full-service carriers (FSC). Binary logit and probit model and latent class mode...
ABSTRACT Attribute sampling plans on quality indices like AQL and MAPD gives the way for Sustainable Quality Region especially for the product at initial stage of production, where the exact quality of the product was not well designed. Optimum information on Acceptable quality level (AQL) and Maximum allowable percent defective would be better for protecting both consumer and producer in terms of SQR along with AQL or MAPD. New single sampling plans were developed by suggesting a unique mon...
ABSTRACT Most experimental situations call for standard designs that can be constructed with many statistical software packages. In some situations, however, standard designs are not appropriate or practicable. Computer-aided designs are experimental designs that are generated based on a particular optimality criterion and are generally optimal only for a specified model. In this work designs are generated for non-standard multifactor experiment using D-optimality criterion. The experiment in...
ABSTRACT The recently developed Adjusted Ridge Estimator (ARE) for handling multicollinearity problem in Linear Regression model does not require the use of the biasing or ridge parameter, K, unlike the Ridge Regression Estimators (RRE) rather i t requires a diagonalization of the correlation vector of the explanatory variables and the dependent variable being raised to a power of half In this research, the effects of other powers on the Adjusted Ridge Regression Estimator were investiga...
ABSTRACT The poor are not evenly distributed within the country and they do not share the same socio-economic and demographic characteristics. It is against this background that analysis of the characteristics that differentiate the poor from the non-poor in Ghana cannot be underestimated. Poverty indicators make it possible to analyze the likely determinants and are, therefore, essential for formulating policy interventions that may contribute directly or indirectly to its alleviation. This ...
ABSTRACT The study analyzed imports revenue contributions from six high-risk commodities obtained from the Inspection and Control Services Company at Tema port. The six items were Auto-parts, Rice, Computers and Accessories, Household Electricals, Poultry Products and Used Clothing. The data covered five years from 2004 to 2008. The objective was to obtain revenue estimates of these six items. Another objective was to provide forecasts of yearly total revenue based on the five years revenue d...
ABSTRACT This research is based on the results of Senior Secondary School Certificate Examination (SSSCE) released by the West African Examinations Council in elective and core subjects of study at Potsin T. I. Ahmadiyya Secondary School from 2000 to 2003. The elective programmes of study are General Arts, Business, Home Economics and Technical subjects. The data also includes the gender and religious affiliation of candidates. The main objective of the study is to identify variables that sig...
ABSTRACT The objective of this study is to present empirical evidence obtained through household survey in order to understand which factors are associated with children who obtain a birth certificate, and thus realize their right to a name and legal identity. Discriminate analysis was used to determine the factors that explain the differences between households who register their children and those who do not. 13 independent variables were analyzed against two levels of the dependent variabl...

ABSTRACT This project is based on the results of candidates who sat for the Senior Secondary School Certificate Examination (SSSCE) conducted by the West Mrican Examinations Council (WAEC). The main objective of this project is to determine whether performance in SSSCE core subjects namely Core Mathematics, Integrated Science, English Language and Social Studies for the five-year period from 2001 to 2005 depended on sex. The data were obtained from the West African Examinations Council-for th...
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 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 ...
