Source discrepancies

What the warehouse found when it checked this series: the same figure from two agencies, splice overlaps, published rates against ones recalculated from the index, and outliers.

  • Error in the source

    The two base years overlap for 36 months (Jan 2014 – Dec 2016). Over those months the ratio between them runs from 0.0478 to 0.488; the splice uses 0.479. Compared with LK.CPI.CCPI.2006-07.CORE.M.

    Splice overlap: 0.048 and 0.488, difference 0.44.

    36 overlapping months 2014-01-01..2016-12-01, factor 0.478700; left out of the factor: 2016-05-01

    The 2016-05 typo falls inside the 36-month overlap, which is why the ratio spread is so wide where every other splice spans a few per cent. An earlier version of this note said the splice used the median and was unharmed; it used the mean, and the typo pulled the 2006/07-to-2013 core factor from 0.6204 to 0.6049, leaving the spliced core index about 2.4% too low for 2003-2013. The splice now leaves out any month more than 50% from the overlap's median - wide enough that the genuine drift between differently weighted indices is kept - and names it in the check.

  • For information

    The two base years overlap for 13 months (Jan 2022 – Jan 2023). Over those months the ratio between them runs from 0.767 to 0.778; the splice uses 0.772. Compared with LK.CPI.CCPI.2021.CORE.M.

    Splice overlap: 0.767 and 0.778, difference 0.012.

    13 overlapping months 2022-01-01..2023-01-01, factor 0.771583

    Every splice reports the spread of its overlapping-month ratios so the chain factor can be judged. A few per cent is normal.
