ICP 6th Regional Workshop for 2011 round in Western Asia Region; 21 – 27 January 2013; Istanbul, Turkey Diagnostic Tables

Outline Quaranta Tables (QT) Dikhanov Tables (DT) Skainov Tables (ST)

QT Main terms - PLI 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.

QT Main terms - PLI

QT Main terms - PLI 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.

QT Main terms - CV Country variation coefficient, which measures dispersion among a country’s PPP-Ratios for a Basic Heading. Basic Heading variation coefficient, which measures dispersion among all the PPP-Ratios for a BH.

QT Main terms - CV

QT Main terms: XR-Price and XR-Ratio 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.

QT Main terms: PPP-Price and PPP-Ratio 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.

DT Main terms - STD 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.

DT Main terms – ER (LCU/USD) Market exchange rates of countries expressed as the number of local currency units per US dollar.

DT Main terms – Rebased XR Exchange rates rebased to the numéraire currency. Number of local currency units per unit of numéraire currency.

DT Main terms – PLI 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.

DT Main terms - CV Coefficient of Variation: Price observation variation coefficient

DT Main terms – XR Ratio XR Ratio: Price ratios based on XR converted prices. The converted prices expressed as a percentage of their geometric mean.

DT Main terms – Residuals 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.

Skainov Temporal Analysis Table 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. Below 15 or greater Between 15 and 25; -15 and -25 Between 25 and 40; -25 and -40 Greater than 40 or lesser than -40
