A researcher used stepwise regression to create regression models to predict BirthRate (births per 1,000) using five predictors: LifeExp (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 Regression Analysis-Stepwise Selection (best model of each size)
153 observations
BirthRate is the dependent variable
p-values for the coefficients
