Replication Data for: Improving Opinion Poll Reporting: The Irish Polling Indicator

Replication data for Improving Opinion Poll Reporting: The Irish Polling Indicator. This paper describes a statistical method for aggregating the information from opinion polls, following on from earlier work in Australia, Canada and the United Kingdom. Such aggregate estimates provide academic researchers with a time series of support for political parties, and inform the public better about opinion polls by focusing on trends and uncertainty in these estimates. The paper discusses the challenge of aggregating opinion polls in a multi-party setting (compared to the US and Australia) with a limited number of polls available (compared to the UK). It discusses how major sudden political and societal events, which have been common in Ireland since 2007, might be better taken into account in poll aggregation models. Finally, it discusses how these estimates can enhance opinion poll reporting in the media.
