PLI expresses the price level of a given
country relative to another, by dividing the
Purchasing Power Parities (PPPs) by the
current nominal exchange rate (XR).
PLIs can be calculated for individual BHs, or
for aggregates.

Rank of the country based on geometric mean (4);
Minimum PLI;
Maximum PLI;
Unweighted geometric mean of all BH PLIs;
Set upper limit for BH PLIs (here 2 times the geometric mean);
Set lower limit for BH PLIs (here 0.5 times the geometric mean);
Number of missing BH PLIs (hence missing PPPs);
Number of BHs below set threshold in (5);
Number of BHs above set threshold on (6); and
Total number of problematic BHs, a sum of (7), (8) and (9).
If a base country approach is used in the calculation of the PPPs,
missing BHs can be caused either by missing price data for the
given country, or for the base country.
Country variation coefficient, which
measures dispersion among a country’s PPPRatios for a Basic Heading.
Basic Heading variation coefficient, which
measures dispersion among all the PPPRatios for a BH.
XR-Price: the average prices in national
currency in column converted to the
numéraire currency with the exchange rates.
XR-Ratio: Standardized price ratios based on
the XR converted prices. The XR-Prices
expressed as a percentage of their geometric
mean.
PPP-Price: The average prices in national
currency converted to the numéraire
currency with the PPPs.
PPP-Ratio: Standardized price ratios based
on the PPP converted prices. The PPP-Prices
expressed as a percentage of their geometric
mean.
Standard deviation of each country’s CPD or
CPRD residuals for the basic heading or
aggregate. It can be converted to a country
variation coefficient by multiplying by 100.
Market exchange rates of countries
expressed as the number of local currency
units per US dollar.
Exchange rates rebased to the numéraire
currency. Number of local currency units per
unit of numéraire currency.
PLI expresses the price level of a given
country relative to another, by dividing the
Purchasing Power Parities (PPPs) by the
current nominal exchange rate (XR).
PLIs can be calculated for individual BHs, or
for aggregates.
Coefficient of Variation:
Price observation variation coefficient
XR Ratio: Price ratios based on XR converted
prices. The converted prices expressed as a
percentage of their geometric mean.
CPD or CPRD residuals by product and
country. CPD residuals in the DT are equal to
the logarithms of the PPP-Ratios in the QT.
The Temporal Analysis Table was created by
the RO to compare item prices between
quarters for the same country and monitor
the variation percentage from one quarter
to the other. The Variations are highlighted
using various color themes referring to
different levels of variation.
