Since the seismic behavior of the earth’s energy (which follows from the power law distribution) can be similarly seen in the energy realized by the stock markets, in this paper we consider a statistical study for comparing the financial crises and the earthquakes. For this end, the TP statistic, proposed by Pisarenko and et al. (2004), is employed for estimating the critical point or the lower...

Can the choice of words and tone used by the authors of financial news articles correlate to measurable stock price movements? If so, can the magnitude of price movement be predicted using these same variables? We investigate these questions using the Arizona Financial Text (AZFinText) system, a financial news article prediction system, and pair it with a sentiment analysis tool. Through our an...

the main focus in this study is on data pre-processing, reduction in number of inputs or input space size reduction the purpose of which is the justified generalization of data set in smaller dimensions without losing the most significant data. in case the input space is large, the most important input variables can be identified from which insignificant variables are eliminated, or a variable ...

background and objectives: efficient hospital management requires appropriate cost and price strategies. informed decision on costs and prices of healthcare services needs estimation of costs of unit services using microeconomic techniques. there is lack of knowledge and skills for such costing methods in the healthcare sector of developing countries such as iran. this study aims at detail desc...

The main contributors to inequities in health relates to widespread poverty. Health cannot be achieved without addressing the social determinants of health, and the answer does not lie in the health sector alone. One of the potential pathways to address vulnerabilities linked to poverty, social exclusion, and empowerment of women is aligning health programmes with empowerment interventions link...

In this paper, we consider a perturbed compound Poisson risk model with two-sided jumps. The downward jumps represent the claims following an arbitrary distribution, while the upward jumps are also allowed to represent the random gains. Assuming that the density function of the upward jumps has a rational Laplace transform, the Laplace transforms and defective renewal equations for the discount...
