Quaranta table
The Quaranta table is a validation table used during PPP calculation. The table groups results by item or basic heading.
History
The table was first proposed by Vincenzo Quaranta for use in the European PPP program in 1990.[1]
Validation type
The Quaranta table computes various statistics of the data and sees if any of these are outside some safe range. Therefore it performs a logical/deductive validation and does not require e.g. collecting new data or keeping a separate dataset for use in validation.
Validation process
- Comparison of average prices
- Exchange rate ratios
- PPP ratios
- Price Level Index
- Price variation
- Variation of individual price observations
- Variation of items within a basic heading
Usage
Quaranta tables have been used in OECD-Eurostat regional comparisons.[2]Template:Rp
