Abstract Valuable information may be contained in outliers. Data collected from many medical equipment such as the ECG time-series may result in unusual patterns, a situation that may represent disease conditions. Some outliers may therefore provide an insight into crucial information that may lead to the discovery of new knowledge.Due to the diculties involved in the study of outliers, majority of current research works have chosen not to out-rightly reject the outliers but have adopted...
ABSTRACT The Kenya Vision 2030 aims at achieving a 10 percent per annum growth rate in the economy. Investments have been identified as a major channel through which this objective can be met. The government has undertaken various public investments to fuel economic growth. However, for this to be even more effective, private investments have to be taken into consideration. The government has taken various measures such as relying more on external debt to avoid crowding out private investmen...
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...
ABSTRACT The effect of inflation on the stock market has attracted many studies. Fisher theory postulates that the real rate of returns on common stocks do not depend on inflation, indicating that stocks should be independent of inflation. The studies have attempted to investigate how inflation affects the stock market and the studies have mainly used the aggregate stock market index. However, the use of aggregate indices may mislead on the actual performance of sector-specific indices. The ...
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...
ABSTRACT Routine inspections are conducted at various food establishments that yield large data sets, which capture attributes useful for data mining algorithms to predict critical violations. Critical violations related to food establishments cause serious public health problems, which may happen as result of unhygienic environment, leading to food contamination. This study presents predictive models to detect critical violations in food establishments by employing Logistic Regression (LR),...
Abstract: Control charts are considered as powerful tools in detecting any shift in a process. Usually, the Shewhart control chart is used when data follows the symmetrical property of a normal distribution. In practice, the data from the industry may follow a non-symmetrical distribution or an unknown distribution. The average run length (ARL) is a significant measure to assess the performance of the control chart. The ARL may mislead when the statistic is computed from an asymmetric distri...
ABSTRACT The study examined men's involvement in prevention of mother-to-child transmission (PMTCT) ofl-IIV programmes in the Federal Teaching Hospital Ido-Ekiti, Ekiti State, Nigeria. The study aimed at identifying correlates of PMTCT in the hospital. Questionnaires was used to elicit information from eligible respondents in the study area. Response were analysed at univariate by using simple frequency distribution and percentage. Cross- tabulation was done to examine the relationship betwe...
ABSTRACT The study described the neighborhood factors influencing contraceptive use among adolescents in Ile Ife. The problems of unwanted pregnancy and inadequate use of contraceptive methods among adolescents is worse in developing countries like Nigeria due to uneven distribution of contraceptives and lack of knowledge on its uses. This study was carried to examine the neighborhood factors affecting contraceptive knowledge among adolescents in Ile Ife. The study made use of primary data wh...
Abstract Nigeria is a country with one of the world’s highest rate of under-five mortality. Any innovative research aimed at bringing solutions to this problem should be considered worthwhile. This study examined how socio-economic, demographic and cultural factors (called underlying factors), influence under-five mortality in Nigeria by identifying some other direct factors (called proximate determinants) through which the underlying factors influence under-five mortality. It used data fro...

ABSTRACT Problems of pregnancy and birth delivery cause more deaths and disability than any other reproductive health problem. The situation is worse in developing countries like Nigeria due to inadequate access to antenatal care services and lack of utilization. A pregnancy not long after the previous childbirth may result in poor health outcomes for the mother, poor health status for the child and a reduction in probability of survival for both mother and child. There are past studies on m...
Abstract Lack of contraceptives use is major concerns not only in Sub-Saharan Africa but also in many other developing countries in the world especially in Nigeria. Therefore, this study assess the factors that determines contraceptive useamong couples in Nigeria, Data were obtained from 2013 NDHS, and weighted sample of 38,676. Univariate result showed that the socio demographic factor is significant with the contraceptive use. The bivariate analysis revealed that there is a significant ass...
ABSTRACT In Nigeria, not many considerations have been taken into the health of vulnerable children at the Internally Displaced Persons Camp. Hence, the need for more research that will help in designing necessary intervention programme. This study examines the determinants of child health among internally displaced persons in Taraba State, using data from a well-structured questimmaire. Binary logistic regression model was ernployed in multivariate analysis. Findings revealed that women betw...
