%description
Most price indexes are made with a two-step procedure, where
period-over-period elemental indexes are first calculated for a collection
of elemental aggregates at each point in time, and then aggregated
according to a price index aggregation structure. These indexes can then
be chained together to form a time series that gives the evolution of
prices with respect to a fixed base period. This package contains a
collection of functions that revolve around this work flow, making it easy
to build standard price indexes, and implement the methods described by
Balk (2008, <doi:10.1017/CBO9780511720758>), von der Lippe (2007,
<doi:10.3726/978-3-653-01120-3>), and the CPI manual (2020,
<doi:10.5089/9781484354841.069>) for bilateral price indexes.
