Compute price indices using various Hedonic and
multilateral methods, including Laspeyres, Paasche, Fisher, and HMTS (Hedonic
Multilateral Time series re-estimation with splicing). The central function
calculate_price_index() offers a unified interface for running these methods
on structured datasets. This package is designed to support index construction
workflows for real estate and other domains where quality-adjusted price
comparisons over time are essential. The development of this package was funded
by Eurostat and Statistics Netherlands (CBS), and carried out by Statistics Netherlands.
The HMTS method implemented here is described in Ishaak, Ouwehand and Remøy (2024)
