kmte-package: An R Package for Treatment Effects with Censored Outcomes.

Description Details

Description

The kmte R package includes a variety of policy evaluations tools when the outcome of interest, typically a duration, is subjected to right censoring. The content includes estimators and tests related to average, quantile and distributional treatment effects under different identifying assumptions including unconfoundedness, local treatment effects, and nonlinear difrences-in-differences.

Details

In short, kmte implements all estimators proposed in Sant'Anna (2016a) "Program Evaluation with Right-Censored Data", and all tests proposed in Sant'Anna (2016b), "Nonparametric Tests for Treatment Effect Heterogeneity with Duration Outcomes". Both articles are available at Pedro H.C. Sant'Anna webpage, http://sites.google.com/site/pedrohcsantanna/ .

When the treatment is exogenous, i.e. under the unconfoundedness assumption, one can use the following functions:

Alternatively, when the treatment is endogenous and we have a binary instrument, i.e. under the local treatment effect setup, one can use the following functions:

In addition, the kmte package also implements the following nonparametric tests for treatment effect heterogeneity:

  1. Under Unconfoundedness:

    • zcate - compute different tests for the null hypothesis of Zero Conditional Average Treatment Effetcs.

    • zcdte - compute different tests for the null hypothesis of Zero Conditional Distributional Treatment Effetcs.

    • hcate - compute different tests for the null hypothesis of Homogeneous Conditional Average Treatment Effetcs.

  2. Under the Local Treatment Setup:

    • zclate - compute different tests for the null hypothesis of Zero Conditional Local Average Treatment Effetcs.

    • zcldte - compute different tests for the null hypothesis of Zero Conditional Local Distributional Treatment Effetcs.

    • hclate - compute different tests for the null hypothesis of Homogeneous Conditional Local Average Treatment Effetcs.

The module was written by Pedro H.C. Sant'Anna (Vanderbilt University).

A help file with examples will be made available in the near future.
