Assignment Help Basic Statistics
Reference no: EM1314957

A researcher used stepwise regression to create regression models to predict Birth-Rate (births per1000) using five predictors: Life-Exp (life expectancy in years), InfMort (infant mortality rate), Density (population density per square kilometer), GDPCap (Gross Domestic Product per capita), and Literate (literacy percent). Interpret these results. BirthRates2
