Item Modelling of Enugu Monthly Rainfall Using Box and Jenkins Methodology.(Tibiscus University of Timişoara, România., 2018-06-01) Adejumo, A. O.; Oloyede, T. O.; Adejumo, O. A.; Oguntunde, P. E.; Odetunmibi, O. A.; Ikoba, N. A.; Job, O.The paper examined the rainfall distribution of Enugu state in Nigeria. Box-Jenkins methodology was used to build ARIMA model to analyze data and forecast for the period of 15 years, from January, 2002 to December, 2016 and to predict for the future. We observed that the average annual rainfall of Enugu state ranges from 124mm to 179mm. The irregularity in annual rainfall of Enugu State one and half decades ago is a bit large, indicating that climate stability is high in the state. Different time series models were diagnostically checked, and tested for Enugu state and at last an SARIMA (0, 0, 0)(1, 0, 1)12 model is chosen as the proposed best model. The proposed model was used to forecast two years’ monthly rainfall value for the state. The results indicated that relatively there is a tendency of increasing in trend of future rainfall values in the state.Item Quantitative Exploration of Factors Influencing Psychotic Disorder Ailments in Nigeria(Elsevier, 2017-07-25) Adejumo, A. O.; Ikoba, N. A.; Suleiman, E. A.; Okagbue, H. I.; Oguntunde, P. E.; Odetunmibi, O. A.; Job, O.In this data article, records on demographic data, family problem issues, as well as results of medical tests from five major classes of psychotic disorder namely: bipolar; vascular dementia, minimal brain dysfunction; insomnia; and schizophrenia, were collected on 500 psychotic patients carefully selected from the pool of medical records of Yaba Psychiatric Hospital, Lagos, Nigeria, for the period of 5 years, between January 2010 and December 2014, were examined. X-squared Statistic was used to examine each of psychotic disorders to identify demographic (age, gender, religion, marital status, and occupation) and family issues (loss of parent, history of such ailment in the family (family status), divorce, head injury, and heredity of such ailment (genetic) factors that influence them. A clear description on each of these psychotic disorders (bipolar; vascular dementia, minimal brain dysfunction (MBD), insomnia and Schizophrenia) was considered separately using tables and bar diagrams. Data analysis results are as follows: firstly, 40.2%, of the 500 psychotic patients tested positive to bipolar, 40.6% to insomnia, 75.0% to schizophrenia, 43.6% to MBD and 69.2% to vascular dementia. Secondly, female patients were more prone to all the psychotic indicators than their male counterpart except in MBD. Thirdly, the oldest age group (>60 years) is more prone to bipolar and insomnia ailments, while the mid age group (30 – 60 years) is prone to schizophrenia and vascular dementia, and the youngest group (< 30 years) is prone to MBD. Lastly, the factors that influence the ailments are listed: bipolar (age, occupation, marital status, divorce, and spiritual consultation); insomnia (age, occupation, marital status, divorce, and spiritual consultation); schizophrenia (age, occupation, religion, marital status, hereditary, and divorce); MBD (gender, age, occupation, and marital status); and vascular dementia (history of the ailment and spiritual consultation). Bipolar and insomnia are influenced by the same set of factors, which implies that any patient having one is most likely to be at risk of having the other.Item A Study of Prominent Crimes in Kwara State Nigeria(University of Lome, Togo., 2017-06-25) Adejumo, A.

This research work is to: identify the prominent crime types; determine the association that existed between pairs of crime types; reduce the dimension of the data using statistical tools; and classify the crime types in different colonies. Principal Component, Biplot, correlation analysis and other statistical tools were utilized in this paper. The pair wise correlation test of significance table indicated that, out of the 45 pair wise correlations, only 6 are significant at 5% and these include; homicide-suicide, homicide-robbery, suicide-robbery, rape-theft, assault-broken, broken-theft and broken-unlawful. We observed that crime types such as assault, unlawful, broken and theft can be grouped together as the most frequent crimes committed; the prevailing cases occurred in the year 2006 and 2008.
