MODELING HUMAN DEVELOPMENT INDEX USING DISCRIMINANT ANALYSIS By Iwuagwu, Chukwuma E. Nwosu, Moses Obinna Department of Statistics Abia State Polytechnic, Aba Abstract The basic objective of human development is to create an enabling environment for people to live long, healthy and creative lives and it is composite statistic of the life expectancy, education income per capita indicators which are used to rank countries into tiers of human development. The paper determined the critical variab...
ABSTRACT The study adopted a pragmatist approach to assess farmers‟ vulnerability and adaptation to drought in three agro-ecological-locations in Ghana. It analysed the variations in precipitation deficits by using precipitation values for 1983-2014 period. It also assessed the variation in drought vulnerability, farmers‟ adaptation and barriers to drought adaptation. The cross-sectional survey design was utilised. A random sample of 326 farmers and six purposively selected lead farmers p...
ABSTRACT The Minimum Description Length (MDL) provides an attractive basis for statistical inference and model selection. However, little is known about the relative performance of its different formulations in Asymmetric Price Transmission (APT) modelling framework. To explore these issues, the study investigates different formulations of the MDL against commonly used alternatives (AIC and BIC) in terms of their ability to recover the true asymmetric data generating process (DGP) under vario...
ABSTRACT This study investigated the impact of ICT three initiatives as perceived by Wiawso College of Education tutors at an independent school in Sefwi Wiawso. A qualitative data was gathered for this Case Study by administering questionnaire to 43 tutors of the college and two administrative staff. Data were analysed using descriptive statistics. First and foremost, evidence was found of an overall increase in the use of ICT since the three initiatives were implemented. Secondly, the provi...
DEVELOPMENT OF STATISTICAL PROGRAM FOR DISCRIMINANT ANALYSIS FOR MIXED VARIABLES USING R-CODE, By Iwuagwu, Chukwuma E. Ibegbulem, Zebulon O. Nwosu, Obinna M. Ekwuribe, Celestine. Department of Statistics, Abia State Polytechnic, Aba, Abia State. Abstract Discriminant analysis is a statistical technique that tried to predict on the bases of one or more independent variables. Whether an individual or other objects can be placed into a particular category of a categorical dependent variables. T...
The ethanolic extract (crude extract) was successively extracted with n hexane, chloroform, water, 103 aqueous methanol and n_hexane to give the corresponding fractions. The crude exfract, 103 "aqueous methanol, vvater soluble and n-hexane fractions of the root of .c_.africana, were screened for antimicrobial activity and chemical constituents. The n-hexane fraction was chromatographed on a column of silica gel to give a number of fairly pure components. The infrared spectra of the comp...
Studies of physico-mechanical and morphological properties of pure and -cellulose reinforced blends of polystyrene (PS) and poly (vinyl acetate) (PVAc) are reported in this work. The compression moulded articles of the blends of different compositions (10:90, 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, 80:20 and 90:10, PS/PVAc) were tested for mechanical performance, absorption behaviour, void activity and morphological arrangements. Comparison of mechanical properties such as tensile...
The corrosion inhibition of aluminium and mild steel in H2SO4 in the presence of Bromothymol blue, BTB, Dimethyl yellow, DMY, Methyl orange, MO, Titanium (IV) oxide, TO and Cassia Siamea Lam, CSL leaves extract at 303 – 313K was studied using “Absorbance difference” technique. The results showed that inhibition efficiency (%IE) increased with increase in inhibitor concentration (except for BTB, where beyond a “critical” concentration of 0.0007M, it reversed its function and bec...
ABSTRACT Leaf area measurement can be a time consuming process and may require sophisticated electronic instruments. The objective of this research was to develop a simple, and less time consuming method for leaf area (LA) estimation of some leaves of cassava varieties. A method based on the beta mass absorption coefficient of the leaf has been developed and used for the estimation of leaf area of three varieties of cassava and the accuracy and precision of this method has been compared with ...
Internal sorting algorithms constitute a class of util ity programs that are widely used in performing routine computing operations . This thesis examines the t heory and structu res of these algorithms and ill ustrates their basic principles with flowcharts and tabular presentations. PASCAL codes were also developed and implemented for the methods.
ABSTRACT This thesis discusses the difficulties older users encounter with Smartphones and tablets. It goes further to discuss the possible reasons for these difficulties and also suggests a solution in form of an application which will help to improve intuitiveness in the above mentioned devices for older users.
Abstract Public health surveillance is a challenge across the globe. Unexpected disease outbreaks occur even though we have vast knowledge in the field of medicine. Also not being able to forecast the next set of diseases to be reported keeps our medical practitioners less prepared. This problem is heightened in low-income countries that cannot afford the infrastructure that comes with ubiquitous computing methods including Machine Learning on a national scale. There is also a notion that su...
Abstract The modern-day automobile is no longer just an analog and mechanical entity. Currently, the most basic of vehicular functions have been computerized. The dedicated hardware assigned to these tasks are electronic control units (ECU). Automobiles consist of a number of ECUs networked together to ensure proper functioning of the vehicle. The overall safety of the vehicle relies on real-time communication between the ECUs. Intra-vehicular communication is possible because of the Controll...
Abstract The advent of mobile gaming brought about a new age of how video games are regarded in the context of mobility. Previously, a person would have to own a specialized gaming device that enabled them play on the move. Devices such as the PlayStation Portable and Nintendo’s series of GameBoy devices made this a possibility. However, mobile games have always offered a constraint on the type of interactions they offer players. A mobile game is only as enjoyable as the quality of informat...
ABSTRACT The ability to observe current trends in health information and predict the future health status of a country is an important goal of health service institutions. Health information systems are used to accumulate, validate and examine data in order to provide information which is used in the formation of health policies. The fast growth and integration of databases means health scientists now have a huge resource that can be studied to make inferences and reveal valuable trends. Dev...
