On the Order of Growth of Convergent Series of Independent Random Variables

A Class of Convergent Series with Golden Ratio Based on Fibonacci Sequence

In this article, a class of convergent series based on Fibonacci sequence is introduced for which there is a golden ratio (i.e. $frac{1+sqrt 5}{2}),$ with respect to convergence analysis. A class of sequences are at first built using two consecutive numbers of Fibonacci sequence and, therefore,  new sequences have been used in order  to introduce a  new class of series. All properties of the se...

Investigating the long-term relationship between health expenditure and labor productivity in Iran

Background and aims: Growth of labor productivity is one of the most important factors of development and competitiveness of the economy. In targeting economic growth, a significant contribution is being made to improve productivity. Labor productivity in a community has several socio-economic dimensions. Since labor productivity reflects the level of production and performance of people in the...

On the bounds in Poisson approximation for independent geometric distributed random variables

‎The main purpose of this note is to establish some bounds in Poisson approximation for row-wise arrays of independent geometric distributed random variables using the operator method‎. ‎Some results related to random sums of independent geometric distributed random variables are also investigated.

On the Ratio of Rice Random Variables

 The ratio of independent random variables arises in many applied problems. In this article, the distribution of the ratio X/Y is studied, when X and Y are independent Rice random variables. Ratios of such random variable have extensive applications in the analysis of noises of communication systems. The exact forms of probability density function (PDF), cumulative distribution function (CDF) a...
