LOGISTIC REGRESSION ON EFFECT OF TUBERCULOSIS AND MALARIA ON HIV

Logistic regression model deals with the relationship that exists between a dependent variable and one or more independent variables. It provides a method for modeling a binary response variable, which takes values 1 and 0. Further, Logistic regression is useful for situations in which you want to be able to predict the presence or absence of a characteristic or outcome based on values of a set of predictor variables. It is similar to a linear regression model but is suited to models wh...

Modeling the Supply of Pipe Borne Water in Ilorin

ABSTRACTWater as an essential commodity plays a major role in national development, the availability of water through pipe borne to individual, communities, and the country at large will help in achieving the New Millennium Development Goal (MDG7), hence the constant study, analysis and forecast for  supply of water using past water supplied. The supply of pipe borne water from 2009 to 2015 was examined with the aim of developing a working model to forecast future supply of pipe borne water....

STATISTICAL ANALYSIS ON STILL-BIRTH AND LIVE BIRTH-RATE

ABSTRACT Stillbirth remains a public health problem with an estimate of 2.6 million stillbirths in 2015 of which 98% occurred in low- and middle-income countries and over three-quarters of these occurring in Sub-Saharan Africa (SSA) and south Asia. Further, only ten countries carry the burden of over 65% of total stillbirths in the world including Nigeria in the second position. The objective of this analysis is to estimate stillbirth rates and identify the determinants of st...

ANALYSIS OF CURRENCY DEVALUATION IN NIGERIA

ABSTRACT The primary aim of this project is to estimate the long run relationship between economic growth and currency devaluation. This project investigated the impact of currency devaluation on economic growth of Nigeria. This was achieved through a review of literature. In order to generate the necessary data for this research, the Central Bank of Nigeria Statistical Bulletin of and publications of the National Bureau of Statistics were used for the period of 2008 to 2017.

The research design is a descriptive survey which comprises a sample of 383 students randomly selected from a population of YABATECH students. The research instrument is a well-designed questionnaire for students. The statistical tools employed in to analyze the data are frequency and percentage ...

Determinants of Child Mortality in Kenya: Stratified Cox Proportion Hazard Model

This study explores determinants of child mortality in Kenya using the 2008/09 Kenya demographic and health survey (2008/09 KDHS) data. Cox proportional hazard model is used and stratification method was used to handle the non-proportionality of the hazards. Kaplan Meir log rank test is used to explore the data and determine the significant variables that have association with child mortality to be used in the model.The study establishes that there is improvements in child survival...

Modelling Consumer Price Index (CPI) in Kenya for the Period 2000 to 2017 Using Autoregressive Integrated Moving Averages--ARIMA(p, d, q)

ABSRACTThe Kenyan CPI data for the period January 2000 to December 2017, obtained from the KNBS website, was the variable of interest, modelled as a time series variable. R was the package used for analysis. Descriptive statistics such as the mean, median, ACF, PACF, time series plots, histograms, lagged scatter plots and qqplots were employed to assess the non-stationarity of CPI after which appropriate smoothing techniques such as differencing were made use of to detrend the data. Formally,...

CHI-SQUARE ANALYSIS ON THE EFFECT OF LACK OF PRACTICAL TOOLS ON THE ACADEMIC PERFORMANCE OF POLYTECHNIC STUDENTS

ABSTRACT    This research work was focused on the EFFECT OF LACK OF PRACTICAL TOOLS ON THE ACADEMIC PERFORMANCE OF STUDENTS in The Ibarapa Polytechnic, Eruwa.    The objectives and purpose of the research work is to determine whether factors such as lack of practical tools, lack of enough practical lecturers, improvising of practical tools has any effect on the academic performance of students, also, to determine if students can cope with academics without adequate practical and equipme...

Application of Nented Design on the Effect of Feeds and Seasonal Variation on Dairy Milk Yield (A Case Study of Napri Shika, ABU Zaria)

ABSTRACTThe present study was conducted at Ahmadu Bello University, Zaria. The aim of the study was to determine the effect of feeds (cotton seed cake, yeast supplement, cow milking ration) and seasonal variation (dry and rainy season) on dairy milk yield. A total of 21 mid lactation cows were fed with cotton seed cake, yeast supplement and cow milking ration in the two seasons respectively   and   the   volume   of   milk   produced...

Bayesian Analysis of 2014 FIFA World Cup Matches Played and Goals Scored.

Abstract: This study was aimed at determining the average performance of teams that participated at the 2014 World Cup in terms of goals scored. Bayesian approach was used to analyze this problem. There was an update of belief about the average goals scored in the tournament through the conjugate Gamma prior and the Poisson likelihood. Using the conjugate Gamma prior and Poisson likelihood, the average goals scored per team was 1.3354 and a posterior standard deviatio...

MODELING OF HEALTH RELATED QUALITY OF LIFE AMONG DIABETES PATIENTS USING INTEGRATED FUZZY INFERENCE SYSTEM AND LINEAR REGRESSIONS (1)

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...

THE STATISTICAL ANALYSIS OF THE NUMBER OF ADMITTED AND RELEASED CHILDREN IN THE MOTHERLESS BABIES HOME

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 ...

Bayesian Estimation of Parameters of A Linear Regression Model With Correlated Explanatory Variables

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 corr...

REGRESSION METHODS IN THE PRESENCE OF HETEROSCEDASTICITY AND OUTLIERS

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 heteroscedastic...

STATISTICAL ANALYSIS OF FACTORS AFFECTING STUDENTS’ ACADEMIC PERFORMANCE IN TERTIARY INSTITUTIONS

School, colleges and universities have no worth without student. Students are most essentialasset for any educational institute. The social and economic development of the country isdirectly linked with student academic performance. The determinants of students' performancehave been the subject of ongoing debate among educators, academics, and policy makers. Therehave been many studies that sought to examine this issue and the findings of these studies pointout to hard work and discipline, pr...
