Abstract
After showing that the estimates provided by three main ecological inference methods are heavily biased when compared to multilevel logistic models applied to a set of real individual data, the paper argues that ecological bias can be corrected only by accounting for relevant covariates. In addition, a data generating mechanism where bias cannot even be corrected by using covariates is described.File in questo prodotto:
