This dataset example introduces Cook's Distance (or Cook's D), a statistic that measures the relative influence of each individual case in a sample of data on the results of a regression analysis. It is used to discover whether one or more cases have such a large effect that they might distort the overall results of the regression. This example uses a data subset from the WHO Global Health Observatory Data 2012 to conduct a simple regression that examines whether the International Health Regulation (IHR) food safety score of a country predicts the 60-year-old life expectancy of a country.
