Following a meta-analysis approach as a special case of multilevel modelling, we are interested to identify the potential sources of dissimilarities in accuracy measures of pre-election polls, carried out in Parliamentary elections in Italy from 2001 to 2008. Multilevel model approach decomposes variance components as well as meta-analysis random models but differently from traditional meta-analysis, multilevel approach makes estimate procedure easier and more flexible.
