In most counties, statistical authorities collect data on the number of deaths in each age group. These data enables the calculation of life expectancy as well as the calculation of death and survival probabilities for each age group. In this paper, we develop an easy-to-use tool to estimate the...

This article examines the connection between elements of nature, such as wind velocity, temperature, moon phases, earthquakes and hours of daylight, and the yield of the major index in the Israeli stock exchange.

The estimated PCP equation includes a significant intercept that points to the possibility...

We present a theoretical model that enables to predict population distribution according to fertility and survival rates for each age group. Using World Bank data, we estimated the relation between fertility rate of change and survival probabilities. Our findings show that fertility rate of...

In this paper, we calculated the average daily return and the Betas of Israeli stocks for the period April 1st 2009 – April 1st 2010. The correlation coefficient between return and Beta is 0.47. Although we find that the econometric relation between return and Beta is statistically...
