ivDiag

ivDiag is toolkit for estimation and diagnostics with instrumental variable (IV) designs. It provides R implementations of the guidelines proposed in Lal et al. (2023), enabling researchers to obtain reliable and robust estimates of their IV models.

Examples: R code used in the tutorial can be downloaded from here.

Installation

You can install the ivDiag package from CRAN:

install.packages("ivDiag", repos='http://cran.us.r-project.org')

You can also install the up-to-date development version from Github:

library(remotes)
install_github("apoorvalal/ivDiag")

ivDiag depends on the following packages, which will be installed automatically when ivDiag is being installed:

require(foreach) 
require(future)
require(doParallel)
require(lfe)
require(fixest)  
require(ggplot2)
require(ggfortify)
require(wCorr)
require(haven)
require(glue)
require(patchwork)
require(testthat)

You can use the following code to install the required packages:

install_all <- function(packages) {
  installed_pkgs <- installed.packages()[, "Package"]
  for (pkg in packages) {
    if (!pkg %in% installed_pkgs) {
      install.packages(pkg)
    }
  }
}

packages <- c("foreach", "future", "doParallel", "lfe", "fixest", "ggplot2", 
              "ggfortify", "wCorr", "haven", "glue", "patchwork", "testthat")
install_all(packages)
