Attaching Locks and Variables to Ravels

Attaching Locks and Variables to Ravels

The BIS is 2010, so all indices are 100 during 2010), and the annual rate of change of house prices, with data on both Nominal and Real (CPI-deflated) prices. To analyse the data, it is useful to separate it into House Price Index information and House Price Inflation information, and to focus on Real rather than Nominal Prices. That is done by attaching the output of the Ravel to Locks, and the Locks to named Variables that you create.

Figure 29 shows two variables HPIReal and ∆ HPI Real . They are joined to the Ravel via locks, and once a lock is closed, the output from that lock remains the same, even if the selection on the source Ravel is altered.

data rather than the entire source file. The house price inflation data in Figure 29 suggests a possibly useful piece of analysis: on average, house prices in Advanced economies fell during 2023. To see whether this was a common phenomenon or isolated to a few countries, why not compare the average for all advanced countries (the first entry on the Reference Area axis) to the data for each advanced country?
