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.

  • For information

    The two base years overlap for 12 months (Jan 2022 – Dec 2022). Over those months the ratio between them runs from 0.782 to 0.797; the splice uses 0.79. Compared with LK.CPI.NCPI.2013.HEADLINE.M.

    Splice overlap: 0.782 and 0.797, difference 0.016.

    12 overlapping months 2022-01-01..2022-12-01, factor 0.790242

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