A Study of Lifespan in the United States
In this project, a regression analysis study is conducted to see if the average lifespan (LIFE) in the United States is related to the following six characteristics: MALE, the ratio of male to female in percentage, BIRTH, the birth rate per 1000 population, DIVORCE, the divorce rate per 1000 population, BEDS, the hospital beds per 100,000 population, EDUCATION, the percentage of population 25 years or older having completed 16 years of school, and INCOME, the per capita income. In this study, the outliers and the influential observations will be identified by looking at various statistics, such as RESIDUAL, STUDENTIZED RESIDUALS, COVRATIO, and DFFITS. Analysis about what is unusual about these states is also given.
