Income Polarization Index
The DER (or PaF) income polarization index as proposed by Duclos J. Y., Esteban, J. and Ray D. (2004). "Polarization: concepts, measurement, estimation". Econometrica, 72(6): 1737--1772.
House Price Indexes
Compute house price indexes and series using a variety of different methods and
models common through the real estate literature. Evaluate index 'goodness' based
on accuracy, volatility and revision statistics. Background on basic model construction
for repeat sales models can be found at: Case and Quigley (1991)

Soil Quality Index
The overall performance of soil ecosystem services and productivity greatly relies on soil health, making it a crucial indicator. The evaluation of soil physical, chemical, and biological parameters is necessary to determine the overall soil quality index. In our package, three commonly used methods, including linear scoring, regression-based, and principal component-based soil quality indexing, are employed to calculate the soil quality index. This package has been developed using concept of Bastida et al. (2008) and Doran and Parkin (1994)
Working with Index Numbers
A set of utilities for manipulating index numbers series including chain-linking, re-referencing, and computing growth rates.
Calculation of the Standardized Temperature Index
A set of functions for computing the Standardized Temperature Index (STI).
Binary and Categorical Image Similarity Index
Computes a structural similarity metric (after the style of
MS-SSIM for images) for binary and categorical 2D and 3D images. Can be
based on accuracy (simple matching), Cohen's kappa, Rand index, adjusted
Rand index, Jaccard index, Dice index, normalized mutual information, or
adjusted mutual information. In addition, has fast computation
of Cohen's kappa, the Rand indices, and the two mutual informations.
Implements the methods of Thompson and Maitra (2020)
Index Construction for Time Series Data
Derivation of indexes for benchmarking purposes. A methodology with flexible number of constituents is implemented. Also functions for market capitalization and volume weighted indexes with fixed number of constituents are available. The main function of the package, indexComp(), provides the derived index, suitable for analysis purposes. The functions indexUpdate(), indexMemberSelection() and indexMembersUpdate() are components of indexComp() and enable one to construct and continuously update an index, e.g. for display on a website. The methodology behind the functions provided gets introduced in Trimborn and Haerdle (2018)
Multidimensional Poverty Index (MPI)
A set of easy-to-use functions for computing the Multidimensional Poverty Index (MPI).
An Implementation of the Stratification Index
An implementation of the stratification index proposed by Zhou (2012)
Repertoire Dissimilarity Index
Methods for calculation and visualization of the Repertoire
Dissimilarity Index. Citation: Bolen and Rubelt, et al (2017)
