A mixed membership model for rank data is outlined and illustrated through the analysis of voting in the 2002 Irish general election. This particular election uses a voting system called proportional representation using a single transferable vote (PR-STV) where voters rank some or all of the candidates in order of preference. The data set considered consists of all votes in a constituency from the 2002 Irish general election. Interest lies in highlighting distinct voting profiles within the electorate and studying how voters affiliate themselves to these voting profiles. The mixed membership model for rank data is fitted to the voting data and is shown to give a concise and highly interpretable explanation of voting patterns in this election. | Type of material: | Book Chapter | Publisher: | CRC Press | Keywords: | Proportional representation; Voting; Ireland; Statistical analysis | Other versions: | https://www.crcpress.com/Handbook-of-Mixed-Membership-Models-and-Their-Applications/Airoldi-Blei-Erosheva-Fienberg/9781466504080 | Language: | en | Status of Item: | Peer reviewed | Is part of: | Airoldi, E.M.,Blei, D.M., Erosheva, E.A. and Fienberg, S.E.
