Artificial price and quantity data of the Consumer Price Index Manual

Source: R/data.R
cpi_ch19.Rd

The artificial data set of Chapter 19 of the Consumer Price Index Manual (ILO et al. 2004, Tables 19.1 and 19.2): prices and quantities of six commodities in five periods. The Manual gives the chained Laspeyres, Paasche, Fisher and Tornqvist price indexes of these data (Tables 19.5 and 19.11), which the package reproduces: a Divisia quantity index is a Tornqvist index with the user costs as prices, so dmai() with the prices as x and the quantities as user_cost gives the Manual's price indexes (the two roles are symmetric in these formulas).

Usage

cpi_ch19

Format

A data frame with 5 rows and 13 columns: period (1 to 5), p1, ..., p6 (prices) and q1, ..., q6 (quantities).
