Simple Blinding Index for Randomized Controlled Trials

Computes a simple blinding index for randomized controlled trials introduced in Petroff, Bacak, Dagres, Dilk, Wachter: A simple blinding index for randomized controlled trials. Contemp Clin Trials Commun. 2024 Nov 26;42:101393. . PMID: 39686958.

Predictive Information Index ('PII')

A simple implementation of the Predictive Information Index ('PII') using mutual information and entropy from the 'infotheo' package. For related methodology, see Wells (2025) < https://github.com/TheotherDrWells/piiR>.

Calculate the Dutch Air Quality Index (LKI)

Calculates the dutch air quality index (LKI). This index was created on the basis of scientific studies of the health effects of air pollution. From these studies it can be deduced at what concentrations a certain percentage of the population can be affected. For more information see: < https://www.rivm.nl/bibliotheek/rapporten/2014-0050.pdf>.

Within Outlying Mean Indexes: Refining the OMI Analysis

Complementary indexes calculation to the Outlying Mean Index analysis to explore niche shift of a community and biological constraint within an Euclidean space, with graphical displays. For details see Karasiewicz et al. (2017) .

Forward Selection using Concordance/C-Index

Performs forward model selection, using the C-index/concordance in survival analysis models.

Index of Multiple Deprivation Data for the UK

Index of Multiple Deprivation for UK nations at various geographical levels. In England, deprivation data is for Lower Layer Super Output Areas, Middle Layer Super Output Areas, Wards, and Local Authorities based on data from < https://www.gov.uk/government/statistics/english-indices-of-deprivation-2019>. In Wales, deprivation data is for Lower Layer Super Output Areas, Middle Layer Super Output Areas, Wards, and Local Authorities based on data from < https://gov.wales/welsh-index-multiple-deprivation-full-index-update-ranks-2019>. In Scotland, deprivation data is for Data Zones, Intermediate Zones, and Council Areas based on data from < https://simd.scot>. In Northern Ireland, deprivation data is for Super Output Areas and Local Government Districts based on data from < https://www.nisra.gov.uk/statistics/deprivation/northern-ireland-multiple-deprivation-measure-2017-nimdm2017>. The 'IMD' package also provides the composite UK index developed by < https://github.com/mysociety/composite_uk_imd>.

Spatial Dispersion Index (SDI) Family of Metrics for Spatial/Geographic Networks

Spatial Dispersion Index (SDI) is a generalized measurement index, or rather a family of indices to evaluate spatial dispersion of movements/flows in a network in a problem neutral way as described in: Gencer (2023) . This package computes and optionally visualizes this index with minimal hassle.

Matrices for Repeat-Sales Price Indexes

Calculate the matrices in Shiller (1991, ) that serve as the foundation for many repeat-sales price indexes.

Turn Vectors and Lists of Vectors into Indexed Structures

Package designed for working with vectors and lists of vectors, mainly for turning them into other indexed data structures.

Rmetrics - Modelling Extreme Events in Finance

Provides functions for analysing and modelling extreme events in financial time Series. The topics include: (i) data pre-processing, (ii) explorative data analysis, (iii) peak over threshold modelling, (iv) block maxima modelling, (v) estimation of VaR and CVaR, and (vi) the computation of the extreme index.
