ui: R-package

ui is an R-package which provide confidence intervals (sampling variation) and uncertainty intervals (sampling variation+uncertainty due to non-ignorability assumptions) for (i) for regression (linear and probit) parameters when outcome is missing not at random (non-ingorable missingness); (ii) for double robust and outcome regression estimators of average causal effects (on the treated) with possibly unobserved confounding.

Keywords: Double Robust estimator, Regression Imputation estimator, Average Causal effect, Estimation with missing outcome data, Estimation with non-ignorable dropout.

Commands to install ui in R:

install.packages("devtools"); library(devtools)


install("ui"); library(ui)
