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 collections of functions that revolve around this work flow, making it easy to build standard price indexes, and implement the methods described by Balk (2008, ISBN:978-1-107-40496-0), von der Lippe (2001, ISBN:3-8246-0638-0), and the CPI manual (2020, ISBN:978-1-51354-298-0) for bilateral price indexes.

Title: Predictive Information Criteria for Model Selection
person("Javier", "Flores", , "javenrflo.pro@pm.me", role = c("aut", "cre"),
Description: Computation of predictive information criteria (PIC) from select model object classes
for model selection in predictive contexts. In contrast to the more widely used Akaike
Information Criterion (AIC), which are derived under the assumption that target(s) of prediction
(i.e. validation data) are independently and identically distributed to the fitting data, the PIC
are derived under less restrictive assumptions and thus generalize AIC to the more practically
relevant case of training/validation data heterogeneity. The methodology featured in this package is based on Flores (2021) <https://iro.uiowa.edu/esploro/outputs/doctoral/A-new-class-of-information-criteria/9984097169902771?institution=01IOWA_INST> "A new class of information criteria for improved prediction in the presence of training/validation data heterogeneity".
