Analyze and prediction of expenses for public health in G7 countries

This article represents an analysis were made using data of expenses for public health in G7 countries. We can see the expenses for public health in G7 countries spent during 10 years in 2000-2010. These expenses rise every year. We built a trend line in MS Excel to analyze correlation rates. Our analysis showed rather high correlation coefficients R2. For example, these coefficients R2 for three countries: USA, Germany and France have the following bounds: 0,9606 ≤ R2 ≤ 0,9997. Six diagrams which are presented in the article allow us to understand how the expenses of USA for public health change. These diagrams show us the following mathematical dependences: linear, logarithmic, exponential and polynomial approximations. These diagrams also present mathematical functions and correlation coefficients R2. We have got high correlation coefficients R2 so we can predict future meanings of expenses for public health in G7 countries with high reliability up to 2015.
