This is an approach that obtains the population average effect accounting for the fact that observations within individuals are likely to be more similar than those between individuals. A generalized estimating equation is an estimation procedure 13 for dealing with clustered data, and is seemingly very popular in disciplines trained with a biostatistics perspective, but perhaps not too commonly used elsewhere. GEE can be used to fit Generalized Linear Models (GLMs) when the data have a grouped structure, and the observations are possibly correlated within groups but not between groups.
