scale_weights

Scale a vector of weights so that they sum to 1.

Most price indexes are made with a two-step procedure, where
period-over-period elementary indexes are first calculated for a collection
of elementary 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>) and PPI manual
(2004, <doi:10.5089/9781589063044.069>) for bilateral price indexes.
