Overview

About

Maintained by Bikram Karmakar1 releasesCRAN page ↗

Implements a heuristic algorithm to build blocks of a given size aiming to maximize similarity within strata across multiple covariates. The blocking structure can be used for causal inference and for sensitivity analysis to unmeasured confounding. A stratified structure gives more flexibility for using multiple instrumental variables and direct treatment vs. control analysis as evidence factors. Karmakar, B., Small, D. S., and Rosenbaum, P. R. (2018). Rosenbaum, P. R. (2010)<ISBN:978-1-4419-1213-8>.

Install

R (source archive)

url <- "https://cran.r-project.org/src/contrib/Archive/blockingChallenge/blockingChallenge_1.0.tar.gz"
pkgFile <- "blockingChallenge_1.0.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (1.0) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.
