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), von der Lippe (2007), and the CPI manual (2020) for bilateral price indexes.
