Unusual or unexpected differences among PPPs (e.g. arising from incorrect weighting data) are investigated. Comparisons with data from previous ICP rounds are used to check the credibility of the latest results. 3.3.5. Revision studies Revisions, as a gauge of reliability, are tracked and mined for the information they may — provide. 3.3.5.1. Studies and analyses of revisions between initial and final results are carried out routinely and used internally to inform statistical processes (see also 4.3.3) i. Revision studies are undertaken on a regular basis. Studies assess the initial estimates for the regional component of the ICP Round against revised or final estimates and comprise: - studies of scale (magnitude of revision and number of time series revised) - studies of direction of revisions. Studies investigate the sources of errors, omissions, and fluctuations in the data and explain the methods of revising the data. ii. Measures are undertaken to incorporate the findings from revision studies in data compilation. Findings from revision studies are used to define the optimal publication cycle that is largely driven by the availability of country data. Findings from revision studies are used to refine preliminary data and data collection programs for the subsequent ICP benchmark Rounds. Adequate documentation on revisions is well maintained and includes description of causes of revisions, methods used to incorporate new data sources, the consultations that took place with countries, and the way data are adjusted. Serviceability Statistics, with adequate periodicity and timeliness, are consistent and follow a predictable revisions policy. Periodicity and timeliness Periodicity and timeliness follow internationally agreed understandings. — Periodicity follows agreed understandings i. The periodicity of the statistics follows understandings reached at the United Nations Statistical Commission.
