In this paper another two-parameter Poisson-Sujatha distribution by compounding Poisson distribution with another two-parameter Sujatha distribution which includes geometric distribution and Poisson-Sujatha distribution as particular cases, has been proposed. Its moments based statistical constants including coefficient of variation, skewness, kurtosis and index of dispersion have been obtained. Maximum likelihood estimation has been explained for estimating its parameters. Goodness of fit of the proposed distribution has been explained with five over-dispersed count datasets from various fields of knowledge and fit has been compared with Poisson-Lindley distribution, Poisson-Sujatha distribution, a generalization of Poisson-Sujatha distribution and two-parameter Poisson-Sujatha distribution.

Nowadays, one of the aim of statistical studies is to provide the future with the models which are easily accessible and simple. Therefore, more suitable distributions are needed to model the data. In this study, a new distribution is generated with exponential marginals Farlie-Gumbel-Morgenstern distribution. Specifications and characteristics of this new distribution are studied. The structure of the proposed distribution is discussed statistically and the parameter estimation for the new distribution is made by known methods. In addition, reliability analysis has performed. Due to the shape and flexibility of the proposed distribution, it is thought to be an alternative to distributions which are used for modeling flow data. Efficiency on the statistical modeling of the new distribution can be detected by using flow data sets in literature. Furthermore, Terme and Sefaatli Creeks' flow-data obtained from Turkish State Water Affairs Directorate are used to model. It is concluded that this new distribution offers a model that can be used effectively in stream flows.

Though the rate of poverty in Ghana has consistently declined over the years, some parts of the country still record substantially high figures [1], and this is a major concern for stake holders. Previous research to identify causal factors has commonly used the binary logit or probit models. These models, however, mask the effect of important intermediate information during the binary transformation of the response variable. This has the potential to misestimate the probability of poverty. In this study, the ordered probit model was used, thus creating a framework that includes the ordinal nature of poverty severity. The model was based on the round 6 dataset of the Ghana Living Standards Survey. Our findings show that poor and extremely poor were negatively affected by rural location, illiteracy, and Savannah ecological zone. Policies to eradicate poverty must therefore aim at optimizing these significant variables contributions to welfare conditions in the country.

Though the SDQ has been used in selected studies in Nigeria, its theoretical structure has not been fully and appropriately investigated in the setting. The present study employs Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to investigate the theoretical structure of the self-reported version of the SDQ in a sample of adolescents in Benue state, Nigeria. A total of 1,244 adolescents from different categories of secondary schools in Makurdi and Vandekya Local government areas of Benue state participated in the study. Preliminary data analyses were performed using descriptive statistics while the theoretical structure of the SDQ was assessed using EFA and CFA. Model fits were assessed using Chi-square test and other fit indices at 5% significance level. Participants were 14.19±2.45 (Vandekya) and 14.19±2.45 (Makurdi) years old. Results of the EFA and CFA revealed a 3-factor oblique model as the best model for the sample of adolescents studied (χ2/df =2.20, p<0.001) with all fit indices yielding better results. A correlated 3-factor model fits the present data better than the 5-factor theoretical model of the SDQ. The use of the original 5-factor model of the SDQ in the present setting should be interpreted with caution.

Mental Illness is a public problem in western societies. Recent reports say that the most frequent conditions of psychiatric hospitalization are related to elderly, over 65 years old, diagnosed with dementia, other organic disorders and depression. And we are seeing increasingly in episodes of urgency, consumption of psychoactive drugs, which can foster the emergence of other comorbidities. The aim of this study was to characterize from a socio-demographic, clinical and functional point of view, older people who staged an emergency episode in a psychiatric hospital. This is a cross-sectional, descriptive and correlational study. The sample consisted of 99 elderly people involved in a psychiatric emergency episode in the biennium 2013/2014 and data were collected from the initial evaluation form (IE). Results: People with dementia have more associated diseases than others with other mental Illnesses. Some are at higher risk for potential episodes of falls and loss of functionality and associated factors. Conclusion. More cognitive and functional impairment, evidenced in the functional dependency cycle. The quality of care in later age, requires a multidimensional and interdisciplinary approach. Initial assessment must be complete and holistic in order to give the best care.

Age- and year- specific rates are widely used in epidemiological modelling studies. As these rates are usually unstable due to small denominators, these require smoothing in both dimensions. We demonstrated the application of a two dimensional nearest neighbour method for smoothing age- and year- specific cardiac procedure and death rates. SAS macros were provided for smoothing two rates successively, however these can be adapted to smooth more than two rates or event counts, if required. We found that for the example data sets, the order of the moving average in both year and age dimensions was three and hence a nine point weighted moving average was justified. We demonstrated that in terms of better calibration and capturing important changes in data, the proposed smoother outperformed a similar smoother assigning maximum weight to the central cell but equal weights around it. The degree of smoothing increased with increase in the assigned central cell weight. In conclusion, because of its simplicity, the proposed nearest neighbour smoother provides a convenient alternative to the existing two dimensional smoothers and is useful in situations requiring smoothing a series of rates or counts in two dimensions. A robust version of the smoother is also available from the author.

Changes in nutritional status and high blood pressure are very common in elderly with mental disorders. Currently, the interest in knowing associated factors to those variables is to prevent morbidity and mortality risk. The study aim was to evaluate the relationship between mental disorders, nutritional status and blood pressure. Its a cross-sectional study in a sample of 99 elderly living in community that had a psychiatric emergency episode. Data were collected from the initial evaluation form (IE). Results show multiple pathologies, cognitive deficits, high blood pressure and change in body mass index (BMI). Conclusions: In most of the sample BMI is associated with several co morbidities and co-exists with a temporal disorientation and arterial hypertension. Prevention is the key to maintaining health and well-being. The changes in body composition associated with the aging process are reflected in increased of fat body mass, at visceral level, and decreased of lean body mass expressed in sarcopenia, decreased of bone mass and decreased of water at the expense of intracellular sector (1). Therefore, the nutrition and health of the elderly have to be framed in an enlarged perspective covering all his life. With aging, come upon changes in eating behavior, which will lead to major differences in the choice of food, influenced in turn by the interaction of several factors: biological, economic, psychological and social ones. The association of changes in Body Mass Index (BMI) with changes in blood pressure predispose the outbreak of severe pathological conditions such as coronary heart disease, heart failure, peripheral arterial disease and kidney failure (2), reasons which pro-active steps are needed. In developed countries, the obvious malnutrition can reach 5-10% of the elderly living in their homes and more than 50% in elderly patients and at the time of hospital discharge (1). As people live longer, the quality of longer life becomes a central issue for personal life and social well-being. Consequently, it is frequent multiple pathologies and also dementia.
