World Bank WDI: Investments in Education and Infrastructure with Participation of State and Private Sector

A R script with an example of an econometric linear regression of the data provided in a Microsoft Excel spreadsheet, that contains some of the World Bank's World Development Indicators, that provides data about the investments performed by countries with participation of the private sector in Telecommunication, Energy, Water and Sanitation, Transport. Other data are population, GDP and GNI, internet users per 100 people, a dummy that assumes value 1 if the country is an OPEP member (and 0 if not), and a table with the income group classification of the countries. All data was collected in World Bank Data site, and contains all the available countries, except those that doesn't contain data about GDP, essential for the analysis that has justified the construction of this little project.

本项目附带一段R脚本，示例实现了基于某Microsoft Excel（微软Excel）电子表格中数据集的计量经济学线性回归分析。该电子表格收录了世界银行（World Bank）部分世界发展指标（World Development Indicators）数据，涵盖各国在电信、能源、水务与环卫、交通领域引入私营部门参与的投资相关信息；其余数据包括人口、国内生产总值（GDP）、国民总收入（GNI）、每百人互联网用户数，以及一项虚拟变量：若某国为OPEP（石油输出国组织，Organization of the Petroleum Exporting Countries）成员国则取值为1，反之则为0；此外还附带一份各国收入分组分类表。所有数据均采集自世界银行数据官网，覆盖所有现有国家，但剔除了缺失本分析所需GDP数据的国家——GDP数据是支撑本小型项目构建与分析的核心必要变量。
