Comparison of Spurious Correlation Methods Using Probability Distributions and Proportion of Rejecting a True Null Hypothesis

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 ...

Identification of Outstanding Performances in Senior High School Examinations: A Principal Component Approach

ABSTRACT The study looks at identification of outstanding and abysmal performances of students in examinations involving seven common subjects taken in the first year at Ghana Senior High School in Koforidua. The scores of the students, who were grouped into six different program classes, in the seven subjects constituted the data for the study. In order to achieve the objective of the study using this high dimensional data set, a multivariate data analysis technique (the Principal Componen...

Trend Analysis of Diseases Reported at Outpatient Departments: A Case Study of the Greater Accra Region

ABSTRACT This study is about diseases reported at the outpatient departments (OPD) in the Greater Accra Region. The objectives of this study was to find the trend of the various diseases reported at the Outpatient Departments, forecast 2007 reported diseases and finally, to identify the most reported disease(s) within the period. Data was obtained from the Adabraka Polyclinic which is the coordinating center for the region's health statistics. The data covered the period 1996 to 2006. Trend ...

ANALYSIS OF FACTORS THAT INFLUENCE THE CHOICE OF SENIOR HIGH SCHOOL BY JUNIOR HIGH SCHOOL STUDENTS

ABSTRACT The objective of this study has been to determine the major underlying factors that influence the choice of senior high schools. To this end, a survey of 510 BECE candidates in Junior High Schools in Nungua, a community in Accra, was conducted. The students were asked to indicate their opinions on twenty seven variables on a five-point Likert scale. The data generated from the survey were multivariate in structure since 27 variables were recorded on 510 respondents. Factor analysis, ...

STATISTICAL MODELING OF THE GHANAIAN WEATHER USING MARKOV CHAINS: A Case Study of Accra, Kumasi and Tamale, 2003-2007

ABSTRACT In this dissertation, Markov chain was used to model the rainfall pattern and sunshine duration for three regional capitals in Ghana (Tamale, Kumasi and Accra). Data on mean monthly averages and daily figures of measured parameters (sunshine duration and rainfall) for five years were used. To achieve these goals, a statistical basis was presented before adopting the three main approaches for modeling. Transition Matrix shows the short-run behavior of Markov chain; the steady-state pr...

MODELING POVERTY STATUS OF GHANAIANS: A LOGISTIC REGRESSION APPROACH

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 ...

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

ABSRACT The 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...
