SURVEYBIAS: Stata module to compute the B and B_w multinomial accuracy measures for polling bias

Kai Arzheimer ()

Statistical Software Components from Boston College Department of Economics

Abstract: This module estimates by Maximum Likelihood methods various polling accuracy measures for multi-party elections based on a generalisation of Martin, Traugott and Kennedy's two-party predictive accuracy index A. For detailed information on the measures A', B and B_w, see Arzheimer, Kai and Jocelyn Evans: A New Multinomial Accuracy Measure for Polling Bias. Forthcoming in Political Analysis(21) 2013, http://dx.doi.org/10.1093/pan/mpt012 The module consists of three ados: surveybias.ado is for use with a single survey (raw data). surveybiasseries.ado facilitates the comparison of surveys. It calculates accuracy measures from a dataset, where each row contains margins from a single survey. surveybiasi.ado is an immediate command that makes it easy to calculate accuracy measures from published survey results. Two example data sets illustrate the use of surveybias and surveybiasseries. More replication data and scripts are available from my dataverse at http://hdl.handle.net/1902.1/21603
